Zusammenfassung:FIELD: manufacture of composite materials, more particularly manufacture of heating members. SUBSTANCE: in order to manufacture graphite-ceramic material having wide range of specific electrical resistance values raw mix comprises 10-30% crystalline graphite and 70-90 wt % low-melting clay, and products are roasted under conditions that limit air access at 700-800 C. The resulting material has electric resistance from to ohm.m. EFFECT: more efficient preparation method. 4 tblt
