A small amount of LaAlO3 added to a La2O3:3TiO2 starting oxide mixture stabilizes the A-deficient La2/3TiO3 perovskite structure. According to XRD and microstructural investigations of samples prepared in the ternary system at 1400ºC, only the solid solution along the La2/3TiO3-LaAlO3 tie-line extends from at least 4 mol% LaAlO3 to pure LaAlO3
