摘要

The effect of the thermophysical parameters of a cooling medium on the macrokinetics of secondary physicochemical processes that occur in a hermetic chamber after the explosion of a solid explosive charge is studied. The yields of condensed carbon and the content of the diamond phase in it are mainly determined by the temperature of the medium in the chamber after explosion. The maximum yield of detonation diamond synthesized from a trinitrotoluene–hexogen TG50/50 alloy is equal to ～10% of the initial explosive mass and is achieved when the steady-state temperature of the medium in the chamber does not exceed T_m = 550 ± 50 K. As this temperature increases, the yield of detonation diamond decreases approximately in inverse proportion to the temperature, and, at T_m > 2800 K, there is virtually no diamond phase in the explosion products. The conversion of condensed carbon due to the presence of the oxygen-containing components of the explosion products (CO_2, H_2O) begins at a temperature of the medium of above 1550 ± 150 K. The decrease in the final energy release that is experimentally detected in calorimetric studies in the case of an explosion of solid explosives with a negative oxygen balance in an inert gaseous medium or in the case where explosives are surrounded by massive shells results from the endothermic conversion of condensed carbon, which absorbs a significant portion of the explosion energy.
