Abstract

We develop an industrial system for a large scale production of ultradispersed diamond (UDD). The system includes set-ups for synthesis and chemical purification of detonation soot as well as experimental shops for additional and deep purification and modification of UDD.

In detonation synthesis, we use “wet” and “dry” technologies when explosion is carrying out in water and gas atmosphere correspondingly. For purification of detonation soot we use the chemical treatment in bynitric-acid aqueous solution at high pressure and temperature in an autoclave. The process occurs in a continuous regime with a technological cycle of 4–6 days, providing large UDD batches of uniform and reproducible quality. The chemical treatment occurs in 5 temperature zones by varying the velocity of the reactive suspension in laminar and intermediary flow regimes. Non-carbon accumulation in the UDD powder and impurities in the waste acid have been studied. Methods for additional purification of UDD from soluble and insoluble impurities and admixtures are suggested, together with ways of decreasing titanium corrosion.
