| Abstract: | Phase relations in the system Sc2O3-WO3 were characterized. Two stable binary compounds were, found. The 1:3 compound, SC2(WO4)3, melts congruently at 1640°±10°C and forms a simple eutectic with WO3 at ～90 mol% WO3 and 1309°+10°C. The 3 : 1 compound, Sc6WO12, forms a simple eutectic with the 1:3 compound at -69 mol% WO2, and 1580°+10°C. The melting temperature of SC6WO12 was >1600°C. |
