摘要：A diamond-containing material having the following element content ratio inper cent by weight: carbon 75-90, hydrogen 0.6-1.5, nitrogen 1. 0-4.5, oxygen the balance,the following phase content ratio in per cent by weight: roentgen amorphous diamond-like phase 10-30, diamond of cubic modification the balance, and having a porousstructure. 10-20% of the surface of the material consists of methyl, nitryl and hydroxylgroups of two types, as well as functional oxycarbonic groups of the general formulaO═R where R represents ═COH, ═COOH, ═CO, ═C. sub.6 H.sub.4 O or any of theircombinations, and 1-2% of the surface constits of carbon atoms with non-compensatedlinks. A method for obtaining said material consists in detonation of a carbon- containingexplosive substance with negative oxygen balance, or a mixture of explosive substances,in a closed volume in the atmosphere of gases inert to carbon, with an oxygen content of0.1-6.0% by volume, at a temperature of 303-363 K and in the presence of ultradispersed

carbon phase with concentration of 0.01-0.15 kg/m.
