FIELD: chemistry.
SUBSTANCE: implementation of the method for silicon carbide ceramic material production, comprises batch preparation from a mixture of silicon carbide micropowders and sintering activator oxides, moulding of the material preform, preform drying and subsequent sintering, the micropowders mixture is obtained by grinding of a silicon carbide particles and activator oxides mixture with particles larger than 5 microns on a rotary abrading mill where grinding inserts and working chamber lining are made from a ceramic composite material comprising vol. %: diamond - 20-75, silicon carbide - 20-75, silica - 3-40.
EFFECT: increased grinding efficiencyand increased chemical purity of the obtained ceramic material.
