Abstract

The invention relates to carbon chemistry and is embodied in the form of a nanodiamond comprising 90.0-98.0 mass % carbon, 0.1-5.0 mass % hydrogen, 1.5-3.0 mass % nitrogen and 0.1-4.5 mass % oxygen, wherein the carbon is contained in the form a diamond cubic modification and in a roentgen-amorphous phase at a ratio of (82-95):(18-5) in terms of a carbon mass, respectively. The inventive method for producing said material consisting in detonating in a closed space of a carbon-inert gas medium a carbon-containing oxygen-deficient explosive material which is placed in a condensed phase envelop containing a reducing agent at a quantitative ratio between said reducing agent mass in the condensed envelop and the mass of the used carbon-containing explosive material equal to or greater than 0.01:1 and in chemically purifying by treating detonation products with a 2-40% aqua nitric acid jointly with a compressed air oxygen at a temperature ranging from 200 to 280° C. and a pressure of 5-15 MPa.
