CARBON COMPOSITION AND METHOD OF OBTAINING IT

摘要

The invention relates to production of super hard materials. A carbon composition comprises 18-38 % by weight of diamond with the size of particles of 40-120 ANGSTROM and up to 100 % by weight of graphite with the size of particles of 200-1000 ANGSTROM . The method consists in detonation of a carbon-containing explosive substance with a negative oxygen balance in a cooling medium containing 40-60 % by volume of carbon dioxide, no more than 2 % by volume of free oxygen and up to 100 % by volume of a neutral gas. The carbon composition can mainly be used as an abrasive material for superfinishing.
