INTRODUCTION

In the 17 years since the predecessor to this bulletin was published, an enormous body of new thermochemical and equilibrium measurements for minerals has been pub lished, personal computers have become almost universally available, and a number of "internally consistent thermodynamic property databases" (ICTDB) have been published (37, 67, 117, 149,150,159,187, 188, 374). (In this section, references are indicated by numbers in parentheses.) This report is an updated revision and expansion of U.S. Geolog ical Survey (USGS) Bulletin 1452 (361) and entirely super sedes it. As an example of growth of the thennodynamic properties of mineral database, USGS Bulletin 1452 con tained data for 58 silicate minerals whereas in the current set of tables this number has been increased to 141.

The purpose of these tables is to present a critical sum mary of the available thennodynamic data for minerals and related substances in a convenient form for the use of earth scientists. To make the tables as useful as possible, we have tried (1) to include enough auxiliary data so that a single set of tables would suffice for most calculations, (2) to ensure internal consistency, and (3) to provide the means for rapid revision and expansion as new data become available.

The tables in this compilation are divided into three sections. In the first section, values are given for the entropy (8293), molar volume (Vigg), enthalpy of formation

, Gibbs energy of formation (AfG^g), and the log arithm of the equilibrium constant of formation (log Kft29g) for the reference elements, minerals, and other substances of geological interest (properties at 298.15 K and 1 bar). In the second section, coefficients for the polynomial used to represent the heat capacity at high temperature are tabulated together with the temperature limits of applicability. In the third section, values are given for the thennodynamic prop erties at 100 K intervals for temperatures up to 1800 K. The data are arranged in order of their conventional mineralogi- cal groups. Within each group (for example, the oxides) the listing is by alphabetical order of the chemical symbol of the principal cation.

The data have been taken from the original literature, recent critical evaluations, or have been evaluated by the present authors and estimated uncertainties have been assigned to the thennodynamic properties at 298.15 K. The primary sources of data are indicated numerically in the thennodynamic table of properties at 298.15 K, as "S" for the reference to the data for the entropy, "H/G" for the refer ence to the formation properties, and "C" to references to measured heat capacities above 298.15 K. The references are listed in complete form following the tables. The entropy and heat-capacity values tabulated are based almost exclusively on calorimetric measurements whereas the val ues for the enthalpy or Gibbs energy of formation were obtained from both equilibrium and calorimetric measure ments. The values for the thennodynamic properties of the reference elements have been taken from the JANAF tables (67), the CODATA (85) recommended values, or in the case of calcium, from measurement at the USGS (360). For those silicate glasses for which Sf - S§ has been determined calorimetrically and for which the enthalpy of fusion of the crystalline equivalent could be evaluated, the residual entropy (that is, SQ) of the glass has been evaluated and added to the calorimetric entropy to obtain the correct entropy for use in thennodynamic calculations. Glasses and other phases for which Sj - SQ has been measured but for which the residual entropy has not been evaluated are indi cated by a "+" sign and the user must be aware that the

THERMODYNAMIC PROPERTIES OF MINERALS AND RELATED SUBSTANCES

value tabulated does not include the configuration^ entropy.

Although a number of different forms of equations for the representation of the heat capacity at high temperatures have been proposed over the past 10 years, for example Berman (37), Fei and Saxena (104), Richet and Piquet (342), we have retained the form adopted in the previous version of these tables,

Cp = A! + A2 »T + A3-T-2 +

This equation can not be extrapolated beyond its upper limit Inasmuch as most users will have access to a personal computer, the conversion from one form of equation to an alternative form is possible and is left up to the individual user's preference. The entropies listed in the table of coeffi cients for the Cp polynomials corresponds to the tempera ture at the lower limit of the temperature range for the polynomial. This is usually 298.15 K.

For several phases, the existence of multiple transi tions at high temperature makes it impractical to provide a simple polynomial expression for the heat capacity. For such phases, for example Fe, Cui.gS, and several pyrrhotites, we have listed only the heat capacity at 298. 15 K.

For these phases, one must go to the high-temperature table for the particular phase (if tabulated) to get the heat capacity (and entropy) above room temperature.

Internally consistent thermodynamic property data sets for silicate minerals have been published by Haas et al. (149), Holland and Powell (187, 188), Berman (37), Hal- bach and Chatterjee (150), and Saxena and Chatterjee (374) among others. Inasmuch as most of the authors relied on the same sources of calorimetric and equilibrium data to derive their adopted values, it is surprising that significant differ ences in their listed values for such important phases as grossular, anorthite, phlogopite and muscovite exist. For example, between the most frequently cited ICTDB, those of Berman (37) and Holland and Powell (188), the values of

calculated from their listed values of S^g and differ by 5.7, 3.7 and 3.7 kJTnoH for grossular,

anorthite, and muscovite, respectively, and for analbite and muscovite the tabulated entropies differ by 4.4 and 9.1 JmioH'K"1 , respectively. The point is, of course, that inter nal consistency does not imply that the derived values are accurate.

The reason for these discrepancies is most likely in the assumptions that the individual compiler makes concerning the state of internal Al/Si order. For a 1:3 AJ/Si compound such as the alkali feldspars or micas the complete random mixing of the 3 Si and 1 Al over the 4 tetrahedral sites leads to a contribution to the entropy of 18.7 J»mol~1»K~1 . How ever, if the aluminum-avoidance model is valid, the configurational entropy will be considerably smaller and of the order of 13 to 14 J'mol'^K"1 . The aluminum-avoidance model has not been calculated exactly and only approxi

mate values are available. The values for the configurational entropies that have been derived from phase equilibrium studies by Holland and Powell (188) and by Berman (37) are 12.6 and 17.0 J'moH-K-1 for analbite and 16.0 and 15.1 JnnoH'K"1 for sanidine, respectively. It appears that these calculated values for the entropy of disor der do not unequivocally support the aluminum-avoidance model but rather tend to yield a configurational entropy that is greater than that estimated by the aluminum-avoidance value, but definitely less than the fully random model. Any value of AS greater than that calculated from aluminum- avoidance would presumably mean that this model was inapplicable at high temperatures; for example, at tempera tures greater than 1300 K for analbite the disordering entropy would approach 18.7 JmioH'K"1 . Moreover Gold smith and Jenkins (123) have shown that the Al/Si disorder in NaAlSi3Og is a continuous function of the temperature and that it occurs over a range of several hundred degrees (500-1050 K) and occurs without change in symmetry.

As a consequence of these points the question arises whether one can extract meaningful (unique) values for the entropy of the disordered phase of an alumino-silicate from phase equilibrium studies without having additional infor mation on the Al/Si distribution. For this reason, we have adopted the fully random model for tabulating the high- temperature properties for the Al/Si disordered feldspars and micas. For an extended discussion of the contribution to the entropy of silicate minerals arising from Al/Si or mag netic spin disorder, see Ulbrich and Waldbaum (413).

The differences in the derived values for the thermody namic properties of phases in the CASH system is due in part to the existence of two calorimetric values for the entropy of grossular which differ from one another by 4.6 J-moH-K-1 . The value of Westrum et al. (438) was deter mined on a natural sample and involved a substantial cor rection for impurities. The value given by Haselton and Westrum (157) was derived from measurements on a syn thetic sample. The heat capacity of the synthetic sample used by Haselton and Westrum (157) was later remeasured at the USGS by the present authors (359), who found an entropy S°(Ca3Al2Si3Oi2, 298.15 K) of 259.9 J-moH-K-1 which agrees with the Haselton and Westrum value to within 0.2 Jnnol^K"1 (0.08 percent). For this reason we have accepted the Haselton-Westrum value for the entropy of grossular in evaluating the thermodynamic properties of phases in the CASH system.

PHYSICAL CONSTANTS AND ATOMIC WEIGHTS

The symbols and constants used to prepare these tables are listed in the table of contents. The units adopted for reporting the thermodynamic properties are those of the International System of Units (SI). A formal description of

METHODS OF CALCULATION

the SI system is given by Goldman and Bell (122). The rec ommended symbols and terminology used are those from the International Union of Pure and Applied Chemistry (IUPAC), "Quantities, Units and Symbols in Physical Chemistry", by Mills et al. (278) and commonly called the "Greenbook". The Greenbook is also a convenient source for the CODATA values of the fundamental physical con stants, the 1985 atomic weights of the elements, and con tains a detailed description of the SI system of units.

Values for the gas constant (R), the Faraday constant (F), and the Avogadro constant (A) used in the calculations are those adopted by the CODATA Task Group from the least squares evaluation of Cohen and Taylor (75). For con venience, we also give values for the atomic weights for 1985 (scale C12 = 12.000, Mills et al. (278)) in alphabetical order by their chemical symbol in table 1.

REFERENCE STATES

The reference pressure for the standard state adopted for these tables is 1 bar, that is 105 Pascals. For a gaseous phase, C£, (HT - H^g)!"1 , and AfH° are independent of pressure, but the numerical values of 8°, (Gf - H^gyT"1 , AfG° depend upon the choice of pressure. The change in pressure from p = 1 atm (1.0135 bar) to 1 bar yields AS = 0.11 Jnnol-^K"1 . For a condensed phase (liquid or solid), it can be shown that the effect of changing the reference pres sure from 1 atm to 1 bar has only a trivial effect upon all the thennodynamic properties tabulated in this report except for AfG°, where a change will occur if one of the reference ele ments (usually oxygen) is a gas.

The standard states for the condensed elements are the most stable form at 1 bar pressure and the stated tempera ture. For gaseous elements, the standard state is the ideal gas at 1 bar pressure. Data are listed for the elements in their standard reference states, and for a few in nonstandard states; for example, S2 gas and the diamond form of carbon. The reference state adopted for an element above its normal boiling or sublimation temperature is not necessarily its equilibrium state. Thus, at equilibrium, liquid sulfur boils at 1 bar pressure and approximately 716.9 K to a gas com posed of S, 82, 84, 85, Sg, etc., but for our reference table, we have assumed the gas phase to be only 82. For the refer ence state table for sulfur we have followed the JANAF (67) tables procedure using 882.12 K as the fictive boiling temperature at which liquid sulfur is in equilibrium with 82 gas at 1 bar pressure. Because of the convenience of using diatomic sulfur gas in calculations of sulfide mineral equi libria we have included a second set of high-temperature tables for which the reference state for calculating AfG°, and AfH° and log Kf for the sulfide phase is 82 gas. The user is cautioned not to intermix values from the two different reference states in their calculations. In other ambiguous cases, we have chosen either the dominant species in the gas

or that species for which the best thennodynamic data are available as the reference state.

The reference states for AfH°, AfG°, and log Kf of the compounds are the elements in their standard states at 1 bar pressure and the stated temperature.

METHODS OF CALCULATION

Having chosen what we believe are the currently "best available" values for Hf - H&g, or Cj (T), S&g and either AfHlgg or AfGsgg, we have calculated the Gibbs energy function, and the enthalpy, Gibbs energy, and the equilib rium constant of formation at 100 K intervals using the fol lowing relations:

- ST

= AfH^g + TA[(GT -

and

log Kf;r =AfGx(2.30258 RT)' 1 = -AfG^gC^.HST)-1

These values together with Cj, Sj and (H| - H^g)!"1 are tabulated in the third section.

Transitions in heat capacity are treated in the standard manner: heat capacity curves are fit to the experimental val ues above and below the transition; values calculated from an extrapolation of the equation to the transition tempera ture are compared to the experimental values; and differ ences are summed to give an enthalpy of transition that is applied at the transition temperature.

The uncertainties assigned to the properties apply only to the values at 298.15 K. The principal source has been the original report of the experimental data. By convention, the uncertainty interval reported for calorimetric measurements is twice the standard deviation of the mean; that is,

5 = 2[Z(xi -xm)2/n(n-l)]*

where xj is the value for an individual measurement, xm is the arithmetic mean of all the measurements, and n is the number of measurements.

For generating the high-temperature tables, the input data supplied to the computer are the identifying name of the substance, the entropy, the enthalpy of formation at 298.15 K, the number of atoms of each element in the chemical formula, and the coefficients for the heat capacity equation. A commercial spreadsheet is used to compute the formula weight of the compound and values for Sf, AfGT, log Kf,x, CJ, (HT - HSwyr1 . and (GT - at 100 K intervals up to 1800 K. Auxiliary data such as the melting and boiling points and enthalpies of melting and vaporization are also included. In addition, coefficients

from a regression performed on the calculated values of are included. The equation adopted is:

The coefficients for the equations are listed, in scientific notation, at the bottom of the page for the individual high- temperature tables. The equations are given only for those minerals for which the regression yielded a fit of better than 1 percent.

ADDITIONAL COMMENTS

Small numbers of some groups are presented with other groups for convenience and economy. Examples

include tellurides, selenides and arsenides that are included with sulfides and sulfosalts, and methane, cohenite, and ammonia that are included with the elements.

The data available in this publication are also available on diskette for a nominal fee through the Generic Mineral Technology Center for Pyrometallurgy at the University of Missouri at Rolla as a part of the FREED database. FREED is a thennodynamic database program for storing, retriev ing, editing, and manipulating thennodynamic data on a computer. FREED was developed with support from the U.S. Department of Interior's Mineral Institute Program, administered by the U.S. Bureau of Mines, and the U.S. Department of Energy through the Westinghouse Savannah River Plant.

450. Heat capacity of hercynite estimated as CP(FeAI204) = £ CP(FeO) + CP(AI203 ) by Robie. Entropy of

MnS04 and other values estimated by Robie.

451. Enthalpies of solution of members of the nepheline-kalsilite series were reported by Hovis and Roux

(Hovis, G.L. and Roux, J., 1993, Thermodynamic mixing properties of nepheline-kalsilite crystalline

solutions: Am. Jour. Sci., v. 293, p. 1108-1127.). Using enthalpy of solution values calculated

from their equations 4 and 5, ancillary data from (166, tables 1-4), and unpublished enthalpy

of solution data for KCI from Hemingway (AH(soln) = 6.045 -0.0189t(°O), we calculate AfH =

-2090.4 ± 2.5 and-2124.7 ± 2.5 kJ *mor1 , respectively, for nepheline and kaisilite. These results

are in good agreement with values given in (361) of -2092.1 ± 2.4 and-2121.9 ± 1.4kJ*mol'1 ,

respectively, but based on less pure samples (20, 171). These results are significantly less

negative than the formation properties calculated by (188) from a limited number of phase

equilibrium experiments. The calorimetrically determined value of -3037.8 ± 2.8 kJ*mol*1 for

leucite (171, 20) is preferred to that derived by (188) from a limited number of phase equilibrium

data (-3020.0 ± 2.7 kJ-mor1 ).


452. Heat capacity measurements on a synthetic alunite are combined with earlier results by Kelley et al.

(219) to estimate the entropy at 298.15 K. The reaction scheme used by Kelley et al. (219) is

recalculated using modern values for the enthalpy of formation of the reference phases. See,

Hemingway, B.S. and Robie, R.A., 1994, Heat capacity and enthalpy of formation of synthetic

alunite: U.S. Geological Survey Open-file Report 94-688, 8 p.

453. High temperature heat capacities are derived from 244, 299, 402.

454. The Gibbs energy of livingstonite at 298.15 K is estimated from the study of (Sorokin, V.I., Dadze, T.P.,

and Pokronskiy, V.A., 1988, The Gibbs free energy of formation of livingstonite: Geokhimiya, No.

6, 897-900).
