Microcrystallites and Granularity of Detonation Nanodiamonds

At the present moment6 science and technology use detonation synthesis nanodiamonds, obtained both from the carbon of an explosive molecule and from a mixture of explosive with the addition of graphite or soot. In the latter case, the diamonds are larger. The given work investigated the synthesis products, obtained under industrial conditions, while having detonation of a mixture of trinitrotoluene (TNT) with halogen (RDX) and RDX with graphite. The sizes of microcrystallites were estimated by X-ray diffraction analysis and particle grain size according to the measurement of specific surface area, agglomerate in water suspension after treatment by ultrasound. The evolution of particle sizes of nanodiamonds, both in the primary synthesis products and after enrichment from non-diamond forms of carbon and technological impurities6 was shown. The results obtained can be useful for studying the mechanism of synthesis and practical application of detonation ND.
