FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. III-type schungite, powdered phenol binder and a lubricant are mixed. The obtained mixture is rolled. The rolled mass is crushed and sieved. Workpieces are made by compression moulding. The workpieces are loaded into a vacuum furnace and heated to temperature of 1900-2100 K at a rate of 200-300 K/h at furnace pressure of 0.3-1.1 kPa, held for 1-2 hours at maximum temperature and then cooled at said pressure. β-silicon carbide is obtained.
EFFECT: invention increases output of the end product and enables to obtain β-silicon carbide with a stoichiometric composition directly in form of porous articles.
