Abstract

Isothermal sections at 1250 and 1650 °C of the А1203- Zr02- Yb203 phase diagram are plotted for the first time. Phase equilibria are established at these temperatures. No ternary compounds and appreciable solid solution regions based on components or binary compounds are found in the ternary system. A partially pseudobinary section Yb3A5-F triangulating the А1203- Zr02- Yb203 system is established.
