摘要：

The ternary phase diagram of Al2O3-La2O3-TiO2 at 1400-degrees-C was determined with 12 compatibility triangles. Al2O3 stabilizes the A-site-deficient La2/3TiO3 perovskite structure. According to XRD and microstructural investigations, the solid solution extends along the La2/3TiO3-LaAlO3 tie line from at least 4 mol% LaAlO3 to pure LaAlO3. With increasing LaAlO3 content, the stabilized La2/3TiO3 structure changes from orthorombic via tetragonal to cubic.
