Abstract

Recent hydrofluoric acid solution calorimetric data are used to derive standard enthalpies and Gibbs free energies of formation of low-albite, high-albite, NaAlSi3O8 glass, microcline, sanidine, and KAlSi3O8 glass. The data are presented as high-temperature functions from 298.15 to 1400° K.
