The regularities of the inuence of sintering temperature, pressure and duration of isothermal holding during spark plasma sintering on the structure of Al 2 O 3 ceramics not containing activating additives are determined. The revealed interrelations made it possible to determine the direction of the search for the optimal parameters of the sintering regime and formulate the technological recommendations for the sintering of ingots for smallsized end mills.Ill. 4.
