FIELD: chemistry.
SUBSTANCE: initial composition, consisting of the following components, wt %, is prepared: C-60 or C-70 fullerenes - 30-50; heat-conducting component - 10-60; binding agent - the remaining part. The heat-conducting component is selected from the group: wurtzide boron nitride, cubic boron nitride, diamond or their mixtures. The binding agent is selected from elements of the group IVa of the Periodic system or their alloy with copper. The heat-conducting element can be preliminarily covered with the binding agent. The obtained composition is subjected to impact of static pressure from 8 to 13 GPa with heating to 900-2000°C for not less than 20 seconds. A superhard composite material with heat-conductivity to 330 W/m·K, a ratio of microhardness to an elasticity coefficient 0.12 is obtained.
EFFECT: high wear resistance of the material.
