摘要：

It is shown that the phase diagrams of refractory oxide systems based on ZrO2, HfO2, Al2O3, and rare earth oxides underlie the microstructural design of various high-performance materials. Process steps to produce coarse-grained ceramics in the HfO2-ZrO2-Y2O3, ZrO2-Y2O3-Sc2O3, HfO2-ZrO2-Sc2O3, Y2O3-Er2O3, Y2O3-ZrO2, Y2O3-HfO2, Y2O3-Al2O3, Y2O3-SiO2, and Y2O3-La2O3 systems to perform at temperatures up to 2200A degrees C are designed. Process steps to produce high-performance fine-grained composites in the HfO2-ZrO2-Y2O3 (Ln(2)O(3)) (Ln-Dy, Ho, Er, Tm, Yb), ZrO2-Y2O3-Sc2O3, ZrO2-Y2O3-Sc2O3, Al2O3-Zr(Hf)O-2-Ln(Y)(2)O-3 (Ln-La, Nd, Sm, Gd, Er, Yb), and ZrO2-Y2O3-CeO2-Al2O3 systems are designed as well.
