Abstract
A computational method has been derived for the estimation of the molar heat capacity contribution to the Gibbs free energy function (fefTO) above 298°K. This method, which is based on the observed temperature invariance of certain ratios of the integrals of these molar heat capacity contributions, has been applied to the analysis of fefTOdata for metal carbides, nitrides, fluorides, borides, and silicides in the crystalline state. The estimated fefTOfor a given compound is more accurate than that obtained by other known estimation techniques and permits a more accurate calculation of ΔG TO than is possible from the commonly used approximation ΔG TO=ΔG 298O‐ ΔG 298O.Keywords
