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.

GdAlO3-SrO 系统中的类包晶相的热行为

本文介绍了对 GdAlO3-SrO-Al2O3 三元体系内部部分之一的 GdAlO3-SrO 部分的研究结果。在 GdAlO3-SrO 部分，合成了在四方体系中结晶的三种三元化合物 Gd2SrAl2O7、GdSrAlO4 和 GdSr2AlO5。有关其固相形成机制的数据得到了系统化。在空气中 1100-1800°C 的宽温度范围内，对 GdAlO3-SrO 体系中的类包晶相的热稳定性进行了研究。确定了 Gd2SrAl2O7、GdSrAlO4 和 GdSr2AlO5 复合氧化物熔化的一致性，并确定了它们的熔化温度。
