Influence of cooling medium on detonation synthesis of ultradispersed diamond

摘要

The paper assesses the influence of cooling medium on synthesis of detonation nanodiamond by detonation of high explosive mixtures. X-ray diffraction and surface analysis measurements of synthesized samples were performed to investigate the role of the environment of chamber on the efficiency of the detonation nanodiamond production in this method. The X-ray line broadening was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. The results indicated that the amount of detonation nanodiamond decreased with the heat capacity of the medium in the detonation chamber.
