EFFECTS OF GRAPHITIZATION ON THE SYNTHESIS OF ULTRAFINE DIAMOND BY EXPLOSIVE DETONATION

Graphitization plays an important role in the synthesis of Ultrafine Diamond (UFD) during explosive detonation. Carbon phase diagram was studied and a diamond-graphite dynamic equilibrium line is introduced to study the effects of graphitization. The effects of graphitization under different charge conditions and preserving conditions were investigated numerically. It is shown that the graphitization reduces the yield rate of UFD, and the diamond graphitization depends on both the expansion process and the properties of explosives.
