摘要：
The current status of research on high-temperature composite oxide ceramics in the Al2O3–ZrO2–Ln2O3 systems (Ln are lanthanides, Y) is reviewed. It is emphasized that their use as structural materials at high temperatures (up to 1650°C) is promising. Conditions for growing binary and ternary eutectic composites and their properties are described. Weak and strong aspects of these materials are pointed out. The role of phase diagrams in developing high-temperature in situ composites is shown.
