Properties of cubic boron nitride (cBN) powders from 2 to 200 mm particle size have been studied before and after chemical treatment. Impurity compositions of the bulk and surface, density, magnetic, electrophysical, physicochemical, and radiospectroscopic characteristics are considered. Structural
were heated to a sintering temperature between 1250 โข C and 1450 โข C at a heating rate of 300 โข C/min, with a holding time of 5 min in nitrogen atmosphere. The microstructure, phase constitution, microhardness and fracture toughness of the prepared PcBN were then studied. It was shown that the Si 3
