FIELD: technological processes.
SUBSTANCE: invention can be used in production of abrasive materials. Prior to laying the core oil coke is impregnated into the resistance furnace with an aqueous solution of table salt, creating moisture content of petroleum coke of 5–15 wt%. Then core from impregnated petroleum coke is placed into centre of furnace between electric contacts, charge is loaded from silica-containing materials and carbonaceous reducers. Stressed furnace is used to conduct synthesis of silicon carbide.
EFFECT: reduced time of full power of furnace and increased efficiency of furnace.
