FIELD : manufacturing technology.SUBSTANCE : invention can be used in electroplating, polymer chemistry, medicine, biology, as well as in production of oil and polishing finishing compositions. Composite explosive composition is prepared, containing the following components, wt% : tetryl 5–90; TNT 5–70; hexogen 5–45. Composite explosive composition is then blasted in an aqueous shell or shell containing 5?% aqueous solution of urotropin or Trilon B, with weight ratio of explosive composition and shell equal to 1 : (10–14), in medium of gaseous products of detonation of previous detonations of explosive composition as non-oxidative medium.EFFECT : invention provides high-quality detonation nanodiamonds (DND) using simple technology with high output.1 cl, 4 tbl
