We have carried out thermodynamic modeling of the GaI₃–S and ZnI₂–S systems by the method of equilibrium constants and calculated the chemical compositions of the condensed and vapor phases in the temperature range 200–500°C. Our experimental data demonstrate the feasibility of preparing zinc thiogallate by reacting gallium(III) iodide and zinc(II) iodide with sulfur. Synthesis was carried out at a temperature of 450°C over a period 2 h, followed by calcination of the product at 650°C in order to remove the residual iodine. The practical ZnGa₂S₄ yield was 92–94%.Keywordsthermodynamic modelingchemical compositionZnGa₂S₄ yield
