FIELD: chemistry.
SUBSTANCE: invention can be used in powder metallurgy, particularly in producing ultrafine powdered materials based on tungsten carbides used as precursors in production of hard alloys. The method of producing ultrafine powder of a mixture of tungsten carbide and cobalt metal involves producing ultrafine powder of a mixture of tungsten and cobalt oxides by neutralising an aqueous solution of corresponding inorganic salts in the presence of soot, and subsequent carbidisation, carried out by reduction in a current of an inert gas at a rate of 4.5-5.0 l/h at temperature of 1150-1250°C.
EFFECT: obtaining ultrafine powder of tungsten carbide and cobalt metal with particle size of about 300 nm.
