FIELD: chemistry.
SUBSTANCE: invention relates to inorganic chemistry of carbon and specifically to nanodispersed carbon materials and a method of purifying said materials, and can be used in different high-tech fields of industry and science where powdered detonation nanodiamonds are used. Aluminium powder is added to the starting diamond-containing powder in amount of not less than 5 wt %. The mixture is stirred, pressed and the sample is annealed at temperature 900-950°C in a vacuum with residual pressure of not less than 10-3 mmHg for 30 minutes.
EFFECT: deep purification of the surface of the detonation nanodiamonds from impurities is carried out via thermal desorption, which enables to obtain new composite diamond-containing materials in dynamic conditions.
