DETONATION OF LIQUID EXPLOSIVE MIXTURES AT LOW TEMPERATURES,

Abstract

The detonability of mixtures of liquid fuel and oxidizer at low temperatures has been studied for two cases: (1) both oxidizer and fuel are in the solid state; (2) the oxidizer is in the solid state and the fuel in the liquid state. The following mixtures were used: tetranitromethane (TNM)-gasoline, TNM-nitrobenzene, and TNM-benzene (all 70/30 by volume). It is noted that one of the important factors is the oxidizer grain size, the grain of liquid-particle size of the fuel, and their mutual arrangement. The detonability of liquid explosives in the case of rapid cooling which gives rise to a finely divided charge structure with a grain size of 5--10 micron was studied in greatest detail. In this case, the mixture is molecular prior to cooling and mechanical after cooling. In addition, rapid cooling gives rise on crystallization to nitrogen tetroxide bubbles which form additional pores in the charge and may affect the development and initiation of the detonation.
