KINETIC ASPECTS OF THE DETONATION PRODUCTION OF NANODIAMONDS
Nanodiamonds (NA) are a unique material that combines the properties of diamond and the advantages of nanostructures, and the detonation method of its production rightfully belongs to a promising type of basic technologies. The paper investigated diamond and carbon nanostructures of experimental and industrial detonation synthesis, obtained both from explosives (BB) and from a mixture of explosives with carbon additives. The issues of formation of NA in the zone of chemical reactions and the influence of mass-energy and kinetic parameters of BB on the phase composition, microstructure and granularity of NA were considered. The evolution of their changes, both in the primary synthesis products and during subsequent enrichment, is shown. In practice, changes in the microstructure are manifested in an increase in the size of the crystallite and grain in the process of enrichment and subsequent calcination.
