FIELD: manufacture of graphitized products. SUBSTANCE: carbon filler is mixed with petroleum pitch possessing density of 1250-1260 kg/cu.m, volatile products outflow of 46.0-58.0% and softening temperature of 85-120 C. Produced mass is pressed, calcined and graphitized. Obtained products feature heat conduction of 127-136 W/mC, and heat resistance criterion of 16.3-23.8. EFFECT: higher efficiency. 1 tbl
