Features of the effect of sintering temperature, pressure and duration of isothermal exposure during spark plasma sintering on the structure of Al2O3 ceramics without activating additives are determined. The correlation revealed makes it possible to determine the direction for finding optimum parameters of a sintering regime and to formulate the production recommendations for sintering ingots for small end milling cutters.
