N2 - The processes of phase formation in the La2O3-Ho 2O3-SrO-Al2O3 system are investigated in the temperature range 1200-1500°C. The structural characteristics of the compounds described in the studied system are presented. It is established that the formation of (La1-x Hox) 2SrAl2O7 solid solutions proceeds through the formation of LaAlO3, LaSrAlO4, SrAl2O 4, and SrHo2O4 compounds. An increase in the holmium content and the temperature leads to a crossover from the mechanism in which the interaction of LaAlO3 and LaSrAlO4 is a limiting stage to the mechanism in which the decisive role is played by the interactions of SrAl2O4 with Ho2O3 and SrHo 2O4 with Al2O3.
