Thermodynamic properties of minerals and related substances at 298. 15 K and 1 bar (10/sup 5/ pascals) pressure and at higher temperatures

Technical Report ·
OSTI ID:6877512
Selected values for the entropy (S/sup 0/), molar volume (v/sup 0/), and for the enthalpy and Gibbs free energy of formation (..delta..H/sub f//sup 0/, and ..delta..G/sub f//sup 0/) are given for the elements, 133 oxides, and 212 other minerals and related substances at 298.15 K. For those materials for which high-temperature heat-capacity or heat-content data are also available (H/sub T//sup 0/ - H/sub 298//sup 0/)/T, S/sub T//sup 0/, (G/sub T//sup 0/ - H/sub 298//sup 0/)/T, C/sub p//sup 0/, ..delta..H/sub f,T//sup 0/, ..delta..G/sub f,T//sup 0/ and log K/sub f,T/ are tabulated at 100 K intervals for temperatures up to 1800 K. For substances that have solid-state phase changes or whose melting or boiling point is less than 1800 K, we have also tabulated the properties listed above at the temperature of the phase change so that the enthalpy or entropy changes associated with the transformation form an integral part of the high-temperature tables.
