Abstract: | Subsolidus phase relationships in the Ga2O3–In2O3–SnO2 system were studied by X-ray diffraction over the temperature range 1250–1400°C. At 1250°C, several phases are stable in the ternary system, including Ga2O3( ss ), In2O3( ss ), SnO2, Ga3? x In5+ x Sn2O16, and several intergrowth phases that can be expressed as Ga4?4 x In4 x Sn n ?4O2 n ?2 where n is an integer. An In2O3–SnO2 phase and Ga4SnO8 form at 1375°C but are not stable at 1250°C. GaInO3 did not form over the temperature range 1000–1400°C. |
