HIGH-HARDNESS CARBON MATERIAL AND METHOD FOR PRODUCTION THEREOF

摘要

FIELD: chemistry.SUBSTANCE: molecular fullerene Cor fullerene-containing soot with an additive of a sulphur-containing compound is subjected to pressure of 0.2-12 GPa and temperature of 0-2000°C. The sulphur-containing compound used is carbon sulphide, a mercaptan group compound or a product of reacting a mercaptan group compound and elementary sulphur. The structure of the obtained high-hardness carbon material is formed by covalently bonded layers of fullerene molecules which are two-dimensionally polarised along a second-order axis of rotation.EFFECT: hardness of the obtained material is greater than 10 GPa.4 cl, 5 dwg, 6 ex
