Preface

Thermodynamic data for inorganic materials are fundamental for the optimisation of existing process parameters and for investigating suitable parameters for carrying out potential new processes. With the aid of such data, considerable time and costs can be saved by calculating the conditions necessary to produce a material of the required composition and specified purity, with a minimum usage of energy and input materials and with a minimum release of harmful substances to the environment. The reliability of such calculations depends, of course, on the accuracy of the thermodynamic data used and one difficulty facing the user of published thermodynamic tables has been the wide selection of such compilations available. A further difficulty in using such tabulations is the need to maintain compatibility if it is found necessary to use values from more than one compilation. Different standard states, different tabulated functions and even different values for the same substance can quickly lead to uncertainty and errors in application of the numbers. Nearly all currently available compilations of thermodynamic data relate to pure substances. Very few publications of solution properties for inorganic materials exist. There are very, very few processes however, for which the reactants and products can be regarded as simple stoichiometric compounds. Even very small amounts of dissolved gases or other impurities in a product material can seriously impair its properties. On the other hand, many materials in use today are comprised of several deliberately alloyed constituents to achieve desired mechanical and physical properties. Only by including the thermodynamic solution properties of the dissolved species can full account be taken of reactions such as those between an alloy melt and a slag phase, or those involved in forming precipitated phases in a multicomponent alloy, or in vapour deposition of complex coatings on an alloy substrate, etc.. For almost 20 years, members of SGTE have been working together to try to overcome some of these problems by together producing self-consistent and compatible thermodynamic datasets, not only for pure inorganic substances, but also for mixtures of substances in the form of alloys, slags, salt systems, aqueous solutions, etc. Major advantages of the SGTE data are their self-consistency, the fact that they are produced with careful attention to a well-defined quality procedure and that the expertise of SGTE members in various areas of inorganic chemistry and materials science (ferrous and non-ferrous metallurgy, ceramics, slags, nuclear, aqueous, etc.) allows review of the numbers by highly qualified scientists in the fields concerned. The SGTE evaluated data forming this series provide a self-consistent progression from elements and stoichiometric compounds (Volume A) to binary systems including solution phases (Volume B). The possibility to continue to ternary and multicomponent systems is also forseen. The data in the latter would be so presented as to correspond to potential application themes (steels, light alloys, nickel-base alloys, etc.). The fundamental equations used in evaluating the data are given in the introduction to the volumes and the models used in representing the data are described. Each book is accompanied by a CD-ROM allowing computer tabulation of any required function at any temperature, or for selected temperature ranges, for the substances or systems in that volume. Graphical representations are also possible, including phase diagrams for the systems. The first set of four books (subvolume A) will be accompanied by software which also allows calculation, tabulation and plotting of the thermodynamic properties of reaction of substances selected from any of the Parts 1 to 4.

Information on more comprehensive software, allowing complex equilibrium calculations involving not only pure substances, but also solution phases of different types, can be obtained from SGTE members. A list of the SGTE membership is presented in the cover pages of this Volume. In presenting the data in this Series, SGTE would like to give sincere acknowledgement to the contributions of a number of scientists whose efforts have been invaluable in establishing the present SGTE databases. The names are as follows: Prof. E. Bonnier, Dr. M.H. Rand, Prof. O. Kubaschewski, Dr. M. Olette, Prof. O. Knacke, Prof. M. Hillert, Prof. I. Barin, Dr. H.L. Lukas, Dr. C. Bernard, Dr. T.I. Barry, Dr. T.G. Chart and Dr. G.P. Jones. The skilled evaluations originating from members of THERMOCENTER, Russian Academy of Science, are also gratefully acknowledged.

Introduction

The data presented in this series, dealing with pure inorganic substances (IV/19A), binary systems (IV/19B) and ternary and multicomponent systems (IV/19C) have been evaluated and compiled by SGTE. SGTE is a consortium of European laboratories working together to develop high quality thermodynamic databases for a wide variety of inorganic and metallurgical systems [87Ans, 91Din]. The SGTE element data [91Din] conform to the 1990 International Temperature Scale and over the last years have formed the basis for most assessments of binary, ternary and higher order systems appearing in the open literature. Members of SGTE have played a principle role in promoting the concept of “computational thermochemistry“ as a time and cost-saving basis for guiding materials development and processing in many different areas of technology. At the same time, through organisation of workshops and participation in CODATA Task Groups, SGTE members have contributed significantly to the broader international effort to unify thermodynamic data and assessment methods. The SGTE data can be obtained via members and their agents world-wide for use with commercially available software developed by some of the members, to enable users to undertake calculations of complex chemical equilibria efficiently and reliably.

1 Basic equations and functions used

1.1 Heat capacity The heat capacity of the elements and the pure substances in a defined state is represented by a power series of the form C p = a + b ⋅ T + c ⋅ T 2 + d ⋅ T −2

(1)

It is often necessary to use several temperature ranges, without discontinuities, in order to represent the assessed Cp values as accurately as possible. Plots of Cp are presented for each substance, whilst calculated values for selected temperatures or temperature intervals can be obtained using the software accompanying the volumes. It can sometimes be necessary to extrapolate the thermodynamic properties of the solid phases of an element beyond the temperature ranges where the phases are stable. In the SGTE treatment of such data for the liquid phase, it has been assumed that the heat capacity of the liquid should approach that of the SER-phase (Standard Element Reference-phase, which is usually the phase stable at 298.15 K) and similarly, that the heat capacity of all solid phases above the melting temperature should approach that of the liquid. This excludes a proper treatment of glass transformations, but represents a pragmatic solution to the difficulties associated with necessary extrapolations and removes the possibility of phases becoming incorrectly stable at high or low temperatures. The resulting additional T 7 and T –9 temperature terms used are presented in equation (7) below. Alternative extrapolation methods have been used for some elements and new methods are being reviewed for incorporation into the SGTE databases shortly [95Sun].

1.2. Enthalpies of formation and transition and standard entropy The enthalpy of formation at 298.15 K, ∆f H0 (298 K), and the standard entropy at 298.15 K, S0 (298 K), are presented for each substance, together with the enthalpies and temperatures of polymorphic transformations, ∆ trs H and Ttrs. A reference pressure of 100 kPa is used. In addition, the value of H(298.15 K)-H(0 K) is given when available.

1.3. Gibbs energy As most thermodynamic calculations relating to reactions and phase equilibria involving inorganic materials are made assuming constant temperature and pressure, the Gibbs energy is often the most suitable function to describe the thermodynamic properties of the substances involved. The molar Gibbs energy of a pure element i, reference state at 298.15 K,

Gi (T ) , referred to the enthalpy of its standard

H i (298.15K ) , is denoted by GHSERi. This quantity is described as a

function of temperature by the following equation:

SGTE

Landolt-Börnstein New Series IV/19A

Introduction

XIII

GHSER i = 0 Gi (T)− 0 H i (298K ) = a + b ⋅ T + c ⋅ T ⋅ lnT + d ⋅ T 2 + e ⋅ T 3 + f ⋅ T −1

(2)

The same basic equation is also used to describe the Gibbs energy of pure stoichiometric substances. N.B. It is important to recognise that GHSER (normally shortened to G) is not the Gibbs energy of formation at a particular temperature. ∆ f G includes contributions from the entropy of the elements at T and changes in the enthalpy of the elements between 298.15 K and T. From the Gibbs energy, all important thermodynamic properties can be calculated by combining appropriate partial derivatives. In particular the first and second derivatives of equation (2) with respect to temperature are related to the absolute entropy and heat capacity of the substance at the temperature concerned. Experimental values for heat capacity can thus be directly correlated with the coefficients c, d, e and f. S = −b − c − c ⋅ lnT − 2d ⋅ T − 3e ⋅ T 2 + f ⋅ T −2

Using

G = H −T ⋅S

(3) (4)

H = a − c ⋅ T − d ⋅ T 2 − 2e ⋅ T 3 + 2f ⋅ T −1

(5)

C p = −c − 2d ⋅ T − 6e ⋅ T 2 − 2f ⋅ T −2

(6)

Taking into account the need to extrapolate the data for a phase to metastable ranges, as discussed in Section 1.1., equation (2) is modified to give: GHSER i = 0 Gi (T )− 0 H i (298K ) = a + b ⋅ T + c ⋅ T ⋅ lnT + d ⋅ T 2 + e ⋅ T 3 + f ⋅ T −1 + g ⋅ T 7 + h ⋅ T −9

(7)

1.3.1. Influence of magnetic behaviour For substances which display a magnetic ordering (e.g. the elements Cr, Fe, Ni, Mn), the term GHSER is considered for a paramagnetic state and the magnetic contribution is treated explicitly. Thus an additional term is added to the molar Gibbs energy of the magnetic phase. This is equal to: G mag = RTln(β + 1) ⋅ f(τ)

(8)

where τ is T/Tc, Tc being the critical temperature for magnetic ordering and ß the average magnetic moment per atom expressed in Bohr magnetons. The function f(τ) is given as: τ < 1:

f(τ) = 1-[79 τ-1/140p+(474/497)(1/p-1)(τ 3/6+ τ9/135+ τ 15/600)]/A

τ > 1:

f(τ) = -[ τ -5/10+ τ-15/315+ τ-25/1500]/A

A = 518/1125+(11692/15975)(1/p-1)

These equations were derived by Hillert et al. [78Hil] from an expression of the magnetic heat capacity, C pmag , proposed by Inden [81Ind]. The value of p depends on the structure. For example, p has a value of 0.28 for fcc and hcp metals and 0.40 for bcc metals [81Ind]. Gibbs energy equations for the pure elements, of the form given in equation (7), have been published previously as the SGTE data for the pure elements by Dinsdale [91Din].

1.4 Gibbs energy of formation 1.4.1 Binary compounds The Gibbs energy of formation of a binary compound AaBb is expressed as: GA a Bb − a⋅0 H A (298.15K) − b⋅0 H B (298.15K) = f(T )

(T ) is the Gibbs energy of formation of the compound referred to the stable elements

at temperature T. 1.4.2 Gaseous species An expression identical to equation (12) is used to describe the Gibbs energy of formation of gaseous species, with an additional term RT lnP, where P is the total pressure. The reference state for each vapour species is taken to be the pure component at 0.1 MPa pressure.

2 Definitions and reference information The definitions given here, which are relevant to the volumes of tabulated data and accompanying software, are intended to explain the meaning of words commonly used in metallurgical and inorganic thermochemistry; they are not necessarily generally used definitions in all cases. Atom An atom is the smallest possible state of division of an element. Component (see System) Compound A compound is composed of at least two different elements. The phase is not defined. A compound in crystalline form may be made up of individual molecules or it may have extended ionic, covalent or metallic bonding. For example the overall composition of rock salt is governed by the fact that there are equal numbers of Na+ and Cl– ions on two sublattices. The use of the word compound normally implies a stoichiometric composition (i.e. the amounts of the elements are in simple ratio). Element An element cannot be broken down to a simpler chemical form by non-nuclear processes. The phase is not defined and the element may be present as atoms or molecules, e.g. gaseous O, O2 and O3 are different molecular forms of the element oxygen. SGTE

Introduction

Equilibrium At chemical equilibrium the phases present, their composition and internal speciation is such as to minimise the Gibbs energy at a fixed pressure or the Helmholtz energy at fixed volume. When the Gibbs energy is minimum the chemical potentials (partial molar Gibbs energies with respect to composition) of the components are equalised throughout the system, i.e. in every phase. Thus equilibrium can be computed either by minimisation of Gibbs energy or equalisation of chemical potentials. Ion An ion is an atom or molecule carrying electric charge. Isomer Isomers are molecules with the same formula but different structures. SGTE distinguishes between isomers by appending a tag to the formula, e.g. C2Cl2H2_trans and C2Cl2H2_cis. Isotope Isotopes of the same element have the same atomic number but differing atomic weights. For most elements, and for most purposes, the differences in chemical behaviour are insignificant. Hydrogen is an exception and the SGTE substance database incorporates data for deuterium, tritium and some of their compounds using the symbols D and T. Model The word "model", as used in conjunction with the SGTE data, applies to any mathematical description of the properties of a phase, a unary or an interaction as a function of one or more variables such as temperature, pressure, composition and internal distribution of components. The mathematical model is strongly linked to the phase and takes account of structural features of phases for example multiple sublattices and solution on individual sublattices. Within a single phase the same model must be used to describe the mixing between all binary and, if necessary, higher order combinations of unaries. This entails that care must be taken when developing data for a multicomponent system that models and reference states are consistent. "Model" may also have a more restrictive definition in which the parameters in the mathematical description are given definite numerical values. Molecule A molecule is a chemically bonded group of similar or different atoms, eg Cl2 or NH3. The word molecule is most often used for species in the gas phase, but it can be used for species (q.v.) in other phases, including crystalline phases, provided the molecule behaves as a single entity. Phase A phase is chemically and structurally homogeneous and is distinguishable from other phases by its name, structure and properties (mechanical, physical and chemical). Crystalline phases have a definite periodic structure, often with sublattices. In order to define phases uniquely, phase names like fcc and alpha are insufficient. For this reason SGTE has coupled the Pearson symbol to the crystal class for metallic phases, e.g. Fe. Reference state Enthalpy data for all substances are ultimately referred to the enthalpy of the elements in their standard reference states. This corresponds to the stable phase at 1 atm. (101325 Pa) and 298.15 K. (Phosphorous, for which the red allotrope is more easy to prepare and define in a chemically pure form than is the stable white form, is an exception). Thus, for example, the enthalpy of liquid water is referred to gaseous O2 and H2, both at 101325 Pa, via the equation: H2 + 0.5 O2 = H2O

However, the entropy and heat capacity of liquid water are properties of water itself. The enthalpy and entropy of liquid water are defined by: T

H(H2O) = ∆fH298.15(H2O) + ∫298.15 C p (H2O)dT T

S(H2O) = S298.15(H2O) + ∫298.15 C p (H2O)/T dT

(15) (16)

Solution A solution is a homogeneous mixture within a single phase. Local ordering may be present. A phase that includes a variable proportion of unoccupied sites is also a solution but the vacancies do not constitute a component. The data for solutions are defined by reference to the unaries from which they are constituted using the model and data describing the ideal and non-ideal mixing between these unaries. Species A species is an atom, ion or molecule and corresponds to an identifiable constituent of a phase, for example a gaseous molecule or an ion occupying a sublattice. State of matter The states of matter relevant to these tables are solid, liquid and gas. Substance "Substance" denotes any quantity of material having a definite identity. Thus the term comprises anything from an atom or ion upwards. In the SGTE data presented here, a more restricted sense is implied, namely a unary, a stoichiometric compound or a pure gas. System and component A chemical system is defined by a set of chemical entities known as components. In the simplest case these are the elements comprising the system. However, they may also be compounds of these elements, in which case they may be fewer or, less commonly, greater in number than the number of elements. For the example of the three elements C, H and O, the number of components might be 1, ethanol; 2, ethanolwater; 3, C-H-O; or 4, methanol-ethanol-water-benzene, etc. Systems may be closed or open. In closed systems the total amount of the components is fixed, whereas in open systems the composition can adjust to meet some external constraint. Unary The word "unary" is used to define the constituents of a phase. For example in a liquid phase the unaries might be H2O and C2H5OH. The data for these unaries are those of the pure liquids. Unaries are not necessarily experimentally accessible. For example Ni is unstable but data for it are required to model the solution of nickel in the bcc phase of steels. Moreover, to meet the requirements of models for ionic phases with sublattices a unary may carry charge. For example the formation of an inverse spinel AB2O4 might be modelled by the mixing of the four unaries, A3+(A3+)2O4<spinel>, A3+(B2+)2O4<spinel>, B2+(A3+)2O4<spinel> and B2+(B2+)2O4<spinel> which respectively have charges of +1 –1, 0 and -2 only one of which, even in principle, could have an independent existence. Vacancies Sites in crystalline structures are not always 100% populated, indeed interstitial sites may have a very low occupancy. SGTE modelling considers the unoccupied sites as vacancies, which are denoted by Va.

3 Content of the tables 3.1 Tabulated values The following standard format has been used to present the evaluated thermodynamic values for all inorganic substances: At the head of the page on the left hand side is the chemical formula and name for the substance concerned and on the right hand side a reference or references to the major source of the evaluated data contained in the table below. The table itself contains the following: T (Temperature in K) So (Standard entropy in J K-1 mol-1) - the entropy of the substance at 298.15 K and 100 kPa. H298-H0 (Enthalpy in J mol-1) - the difference in the enthalpy of the substance between 298.15 K and 0 K (when available) ∆f Ho (Standard enthalpy of formation in J mol-1) - the change in enthalpy resulting from the formation of the substance at 298.15K from the appropriate proportions of its pure elemental components in their standard reference states, also at 298.15K ∆f So (Standard entropy of formation in J K-1 mol-1) - the change in entropy resulting from the formation of the substance at 298.15 K from the appropriate proportions of its pure elemental components in their standard reference states, also at 298.15 K ∆f Go (Standard Gibbs energy of formation in J mol-1) - the change in Gibbs energy resulting from the formation of the substance at 298.15 K from the appropriate proportions of its pure elemental components in their standard reference states, also at 298.15 K ∆trs Ho (Enthalpy of transition in J mol-1) - the enthalpy difference between two different stable phases of the substance at the transition temperature corresponding to the value of T in the first column ∆trs So (Entropy of transition in J K-1 mol-1) - the entropy difference between two different stable phases of the substance at the transition temperature corresponding to the value of T in the first column type (nature of the transition) abbreviated information on the nature of the phase transition concerned S-S - solid/solid transition S-L - solid/liquid transition For the elements the information is more detailed including the name of the phases.

Introduction

3.2 Figures There are generally two figures accompanying the tabulated values. These are - a plot of the heat capacity, Cp , (in J K-1 mol-1) as a function of temperature (K) for the complete range of temperature for which data are available. The plot comprises curves for the different phases of the substance if phase transitions occur in the temperature range concerned. - a plot of the enthalpy of formation, ∆fH , and Gibbs energy of formation, ∆fG , (in kJ mol-1 or MJ mol-1) as a function of temperature. Phase transitions in the substance and in the elemental components of the substance are reflected in the different curves. The maximum temperature may be limited by the maximum temperature of one of the component of the substance. For the elements in its reference state the second figure is replaced by a table with several properties, including a short version of the SGTE phase designation (i.e. A_MON_Pu instead of ALPHA_MONOCLINIC_Pu) the Strukturbericht, prototype, Pearson symbol and space group [86Mas, 91Din] the atomic number and atomic weight [96IUPAC, 97IUPAC]. The number in parentheses indicates the uncertainty in the last digit. the density [98Pre]

4 Accompanying software, SGTETab SGTETab is a program for tabulating and plotting the thermodynamic properties for pure substances or a chemical reaction using data stored in the SGTE pure substance database. It has been designed for use under the Windows9x or Windows NT operating systems as a full Windows program providing dialogue boxes, menus and context sensitive help in order to guide the user to ask for the table or plot required. As a Windows program it provides printer support. On executing SGTETab first click the ∆H button which opens the tabulation window containing various simple dialogue boxes allowing you to define: -

the substance (in a compact way, e.g. Be6Li2O10 instead of Li2O.3B2O3) or equation the units of temperature, pressure and energy the thermodynamic function to be plotted the range of temperatures to be covered by the calculations the fixed pressure for the calculations the name of the file where tabulated results are to be saved

The substance or equation is defined using the standard chemical nomenclature for the element names, eg mixture of upper and lower case characters Ag, B, Na, AgCl, CaBr2. If the substance is entered without a phase identifier a crystalline state is assumed with no defined phase name. However if data for a particular phase are to be used, the phase name should be entered immediately after the substance within angular brackets e.g. C. If data for gaseous species are required the phase identifier g is used e.g. H2, CH2. Equations are entered with the list of reactants and products separated by an equals sign e.g.:

Ca + Cl2 = CaCl2 The amount of each of the reactants or products could be a fraction or a non-integer if required e.g.: C +0.5O2 = CO Na + 1/2Cl2 = NaCl SGTETab also provides a facility to balance chemical equations automatically. e.g.: Fe2(SO4) 3 = Fe3O4 + SO2 + O2 will auto-balance to give the chemical equation: Fe2(SO4) 3 = 2/3Fe3O4 + 3SO2 +5/3O2 Both tabular and graphical output is provided on clicking the PLOT button. The graphical output may be minimised for comparison with other graphical output, saved on disk or printed out on a connected printer. Optionally the printed information may be sent to a file as specified in the results file dialogue box. By default SGTETAB assumes that the units of energy are joules, temperature in K and pressure in Pa but alternative units may be selected using by clicking on the arrow in the appropriate dialogue box. The default temperature range over which calculations are carried out is 300 to 3000 K in steps of 50 K but this may be truncated depending on the upper temperature range of one or more of the compounds in the chemical equation. The user may, however, select a range of temperatures and step size depending on his own interest. The default pressure is 105 Pa but again this may be changed by the user if he/she wishes to investigate the properties of a chemical reaction or a pure substance at other pressures. A number of different thermodynamic functions may be plotted as a function of temperature including the heat capacity at constant pressure, Cp (the default), enthalpy, H, entropy, S, the Gibbs energy, G, and a function beta. When looking at data for individual substances the heat capacity and entropy represent absolute values while the values of the enthalpy and Gibbs energy are relative to the SGTE defined reference, Hser, the enthalpies of the elements in their standard reference state at 298.15 K. If a chemical reaction is being considered these functions become the change in properties arising from the chemical reaction ie ∆Cp, ∆S, ∆H and ∆G. The function beta for a pure substance is defined as: G/RTln10 where G is the Gibbs energy relative to HSER as defined above. For a chemical reaction the function beta now represents ∆G/RTln10 or the logarithm (base 10) of the equilibrium constant at constant pressure i.e. log10Kp. While SGTETab gives useful information about the stability of individual substances under ranges of conditions it is worth remembering that more powerful facilities are also available from SGTE members to use the data to model chemical and phase equilibria of much greater complexity.
