ISOTHERMAL SECTION OF THE Al₂O₃–TiO₂–Gd₂O₃ PHASE DIAGRAM AT 1400 °С

Abstract

An isothermal section of the Al₂O₃–TiO₂–Gd₂O₃ phase diagram is constructed at 1400 ºС. No new phases or noticeable solubility regions based on components and binary compounds are found in the system. Triangulation of the system is determined by the Gd₂Ti₂O₇ phase, being in equilibrium with Al₂TiO₅ and GdAlO₃ compounds and TiO₂ and Al₂O₃ components. At 1400 °С, the system is triangulated into six secondary triangles; three-phase eutectics are expected to exist in some of them. Quasibinary eutectics are likely to exist in three quasibinary sections of the system.
