The А1₂0₃- Zr0₂- Yb₂0₃ Phase Diagram. I. IsothermaL Sections at 1250 and 1650 °C

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.
