Abstract

The phase stability of a compound is determined by its Gibbs energy, G(T, P) = HTS. The enthalpy (or enthalpy of formation) is often known from direct measurements or from estimates. The entropy S has been much less studied, and that will be the main theme of this paper. For details, the reader is referred to our recent work, which has dealt with, e.g., 3d-transition metal carbides, nitrides, and oxides (Fernández Guillermet and Grimvall, 1989a, 1990, 1992); transition metal diborides (Fernández Guillermet and Grimvall, 1990b); and alkali halides and hydrides (Grimvall and Rosén, 1983; Haglund and Grimvall, 1990), as well as pure transition metals (Fernández Guillermet and Grimvall, 1989b, c; Grimvall et al., 1987). Here we shall add some material on geologically interesting solids.
