BN is boron with the nitrogen high melting compound, which has a high thermal insulation, insulating and semiconducting properties, the low temperature coefficient of linear expansion. BN is an oxidation-resistant out of doors, is not wetted by molten glass, silicon, bronzes, it does not interact with the molten cryolite and aluminum. BN is used for the castable refractory in the precision metallurgical engineering, in the process of refractories manufacturing, for heat insulation and as a part of dielectrics. The main application of the BN manufactured by the PJSC “ZAPOROZHABRASIVE” – super-hard material synthesis: cubic and wurtzitesimilar boron nitride

Boron Carbide (BC) is characterized by extra-hardness: it is the third substance after diamond and cubic boron nitride material, with high wear-resisting property, chemical resistance in aggressive environments, heat resistance, neutron absorption large cross-section, high electric resistance and semiconductor properties. The grinding materials are used for grinding and polishing by loose abrasive grains and in the form of pastes. BC is widely used in the nuclear industry for the control rods manufacturing. BC is used in the process of armor plates and bullet-proof body armor manufacturing.

The BSC grinding materials are widely used in the abrasive tools manufacturing and fixed-abrasives - rougher, cutting-off and grinding; tools on a flexible base - coated abrasives, in the process of loose abrasive grains grinding. The BSC grinding materials are used: in the process of iron and nonferrous metals, carbon, glass and ceramics, stone, concrete, bricks and chamotte, wood substance, plastics, leather, rubber, and other hard, tough, brittle, alloys, and materials of natural and artificial origin treatment; in the refractory and ceramic industries as a component for moldings and antipenetration washes, in the process of crucibles for casting of non-ferrous and precious metals production, for wash troughs. Refractory products of silicon carbide abrasive materials have high thermal conductivity, heat resistance (deformation starting above 1500 C), resistance to acid slags.
