Abstract

The standard molar Gibbs free energies of formation of BaZrO 3, and Ba 2ZrO 4 have been determined by solid-state galvanic cells involving a single crystal CaF 2 as a solid-state electrolyte. The e.m.f. measurements were performed in the temperature range (1073 to 1273) K. The average values of the standard molar enthalpy and the standard molar entropy of formation in the temperature range covered by the e.m.f. measurements have been also estimated. The results have been compared with those obtained by other authors.
