Energy Of Formation

Heat of reaction and free energy of formation at 25 °C were determined from experimental equilibrium yields for the reaction[Formula: see text]in an aqueous solution.The values are 5045 and 1927 cal/mol respectively. Equilibrium constants for the reaction were determined over a temperature range from 20 to 193 °C.

The solid solutions of [Formula: see text] were synthesized by solid-phase reactions from powder components of CaS, BaS, and Ga2S3. The temperature-concentration dependences of the Gibbs free energy of formation of [Formula: see text] solid solutions from ternary compounds and phase diagrams of the CaGa2S4–BaGa2S4 were determined by a calculation method. It was revealed that continuous solid solutions are formed in these systems. The spinodal decomposition of [Formula: see text] solid solutions into two phases is predicted at ordinary temperatures.
