摘要: (Sm1−xYbx)2Zr2O7 (x=0, 0.5, 1.0) powders synthesized by chemical-coprecipitation and calcination method were pressureless-sintered at 1700°C for 10 h in air. Molten V2O5 reacts with to form m-ZrO2 rare-earth vanadates 800°C. The thickness of corrosion scales was investigated evaluate the hot resistance (Sm1−xYbx)2Zr2O7. against molten increases increasing Yb content. mechanisms proposed based on phase diagrams difference discussed terms basicity ceramics.
