FIELD: production of graphitized materials. SUBSTANCE: filler is constituted by burnt pyrolitic coke ground to a grain size under 40 microns, and binder is a high- temperature coal-tar pitch with a softening temperature of 135-150 C. The components are taken in a ratio of 65-72% of coke and 35-28% of coal-tar pitch. The mass is mixed at 250-280 C and the coal-tar composition is milled to a grain size less than 250 microns. After milling, particles larger than 100 microns are removed from molding powder and the blanks are molded at room temperature, burnt and graphitized. EFFECT: higher efficiency. 3 cl, 2 tbl
