The crystallization of amorphous Аl2О3 and the formation of crystallites g-Аl2О3 can efficiently overcome the passivating effect of the surface oxide film on the sintering process of aluminum powder. It has been found that a system of slit-shaped discontinuities of 30-50 nm in size is formed between the amorphous matrix and nanoscale crystallites g-Аl2О3 through which the extrusion of aluminum on the surface of the powder particles occurs caused by thermal stresses then fusion of aluminum islands into a solid metal film and the formation of qualitative contacts between aluminum powder particles take place.
