Abstract
The results of a study of the GdAlO3–SrO section, which is one of the internal sections of the Gd2O3–SrO–Al2O3 ternary system, are presented. In the GdAlO3–SrO section three triple compounds, Gd2SrAl2O7, GdSrAlO4, and GdSr2AlO5, crystallizing in the tetragonal system, are synthesized. The data on the mechanism of their solid-phase formation are systematized. The results of the thermal stability of perovskite-like phases in the GdAlO3–SrO system are presented in a wide temperature range of 1100–1800°C in air. The congruent character of the melting of Gd2SrAl2O7, GdSrAlO4, and GdSr2AlO5 complex oxides is established and their melting temperatures are determined.
