Subsolidus phase relationships in the Ga2O3-SnO2-ZnO system were determined at 1250°C using solid state synthesis and X-ray powder diffraction. The two spinels, Zn2SnO4 and ZnGa2O4, formed a complete solid solution. The optical band gap of the spinel varied with composition from 3.6 eV (Zn2SnO4) to 4.7 eV (ZnGa2O4). All samples were white and insulating except those containing Ga-doped ZnO. The phase relations and physical properties of Ga2O3-SnO2-ZnO were compared with those of In2O3-SnO2-ZnO.
