Abstract
The unfired free carbon in the detonation products of negative oxygen-balance explosives can be converted to the ultradispersed diamond (UDD), with nanometers sizes on the effects of high temperature and high pressure in the reaction-zone. This process was described approximately by the rapid coagulation dynamics of liquid drops. The detonation temperature of explosives and the properties of small particals were used to research the limiting condition of the growth of UDD, and probably, the quasimelting regime of UDD particals can be regarded as this limiting condition. This result was supported by the simple calculation of the growth time of UDD in the reaction-zone.
