Abstract
Vaporization thermodynamics of the Ga2O3-ZnO system was studied by the Knudsen effusion technique in combination with mass spectrometric analysis of the vapor phase in the temperature range 1360-1460 K. The incongruent character of vaporization processes in the whole composition range of the Ga2O3-ZnO system was established. The vapor composition and the partial pressures of the gas phase species were determined. The p-x projection of the Ga2O3-ZnO phase diagram at 1410 K was constructed. The standard molar enthalpy of formation of ZnGa2O4 at 298 K was found to be −1472.8 ± 26.6 kJ·mol−1.
