FIELD: heat treatment of carbon materials, particularly, carbon black in plasma process. SUBSTANCE: method is used for ordering of nanostructure, for increasing of degree of graphitization in carbon black particles. Method consists in improvement of technical grades of carbon black and nongraphitic carbon materials. Heat treatment is carried out in plasma zone where residence time and supplied power are regulated to ensure absence of carbon material sublimation. EFFECT: prevention of conversion of carbon supplied to plasma zone and its transition to new product. 4 cl, 2 dwg
