METHOD OF ISOLATING SUPERFINE DIAMOND FROM DETONATION CHARGE

摘要

FIELD: explosives.;SUBSTANCE: invention concerns superfine diamond, which can be used in various applications, for example to form stable coatings, in composite materials, antifriction lubricants, and the like. Method comprises treating detonation charge in a gas (air, argon, or nitrogen) flow with water steam at 340-400°C and purification with hydrochloric acid.;EFFECT: avoided necessity of using boric acid anhydride for protection of diamond surface, imparted resistance to high temperatures, and increased yield of product.;1 tbl, 3 ex
