Abstract
Isothermal sections at 1250 and 1650 °C have been constructed for the Al2O3-ZrO2-Sm2O3 phase diagram, and phase equilibria at those temperatures have been demonstrated. No ternary compounds are found and nor are areas of solid solutions based on components and binary compounds in the system. Partially quasibinary sections Al2O3-F, SmAlO3-(66.7% ZrO2 · 33.3% Sm2O3), and Sm4Al2O9-F have been detected, which triangulate the ternary system, and a demonstration is given of the mechanism for penetration of a phase Sm2Zr2O7 with the structure of the pyrochlore into the middle of the Al2O3-ZrO2-Sm2O3 system.
