Abstract
The optimal catalyst for a selective oxidation of the nondiamond component of a diamond detonation synthesis product has been determined. The phase composition and oxidation resistance of diamond nanopowders recovered by different methods have been studied. It has been shown the existence of residual nondiamond carbon in diamond powders recovered by a gas-phase oxidation in the presence of copper (II) chloride (CuCl2) and their higher oxidation resistance than of recovered by a mixture of chromium anhydride with the sulphate acid.
