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 1360–1460K. 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 1410K was constructed. The standard molar enthalpy of formation of ZnGa2O4 at 298K was found to be −1472.8±26.6kJ·mol−1.
