Abstract

Previous thermodynamic description of the La₂O₃-Ga₂O₃ system has been updated based on new experimental data on the liquidus and the enthalpies of formation of LaGaO₃ and La₄Ga₂O₉ measured by high-temperature oxide melt drop solution calorimetry as well as calculated from first-principles. The existing contradictions were successfully resolved. Both the phase diagram and thermodynamic data were reproduced with high accuracy by thermodynamic calculations using the CALPHAD method.
