FIELD: chemistry.
SUBSTANCE: invention relates to modification of properties of superhard materials and can be used in synthesis highly pure ultradisperse diamonds. Detonation carbon is processed in supercritical water or in supercritical water with addition of hydrogen peroxide.
EFFECT: modification of surface of nanoparticles of condensed carbon phase containing ultradisperse diamonds, removal and decomposition of non-diamond carbon structures, environmentally safe non-waste technology.
