摘要：

Phase formation in the La2O3-SrO-Al2O3 system was studied. Formation of the perovskite LaAlO3 structure and the perovskite-like LaSrAlO4 and La2SrAl2O7 layered structures in solid-phase chemical reactions is activated only after reaching certain critical temperatures which correlate with the temperatures of of the transition of intergranular formations to the liquid-like state (melting points of two-dimensional nonautonomous phases).
