Abstract: | The phase relations in the Yb2O3Ga2O3CoO system at 1300 and 1200°C, the Yb2O3Ga2O3NiO system at 1300 and 1200°C, the Yb2O3Ga2O3CuO system at 1000°C and the Yb2O3Ga2O3ZnO system at 1350 and 1200°C, the Yb2O3Cr2O3CoO system at 1300 and 1200°C, the Yb2O3Cr2O3NiO system at 1300 and 1200°C, the Yb2O3Cr2O3CuO system at 1000°C, and the Yb2O3Cr2O3ZnO system at 1300 and 1200°C were determined in air by means of a classical quenching method. YbGaCoO4 (a = 3.4165(1) and c = 25.081(2) Å), YbGaCuO4 (a = 3.4601(4) and c = 24.172(6) Å), and YbGaZnO4 (a = 3.4153(5) and c = 25.093(7) Å), which are isostructural with YbFe2O4 (space group: and c = 25.109(2) Å, were obtained as stable phases. In the Yb2O3Ga2O3NiO system and the Yb2O3Cr2O3MO system (M: Co, Ni, Cu, and Zn), no ternary stable phases existed. |
