Beschreibung
Zusammenfassung:	A diamond-containing material having the following element content ratio in per 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 porous structure. 10-20 % of the surface of the material consists of methyl, nitryl and hydroxyl groups of two types, as well as functional oxycarbonic groups of the general formula O=R where R represents =COH, =COOH, =CO, =C6H4O or any of their combinations, and 1-2 % of the surface consists of carbon atoms with non-compensated links. A method for obtaining said material consists in detonation of a carbon-containing explosive 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 of 0.1-6.0 % 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.
