DETONATION OF WATER-GEL EXPLOSIVE

摘要：

The methodology assumes that the heat of detonation of an explosive compound of composition can be approximated as the difference between the heats of formation of the detonation products and that of the explosive,divided by the formula weight of the explosive.For the calculations in which the first set of decomposition products is assumed,predicted heats of detonation of slurry explosives with the product H2O in the gas phase have a deviation of 866 kJ/kg from results with the product H2O in the liquid state.Fine-particle lithium manganate has been prepared by the detonation of slurry explosives of the metal nitrates,M(NO3)x (M = Li,Mn) as oxidizers and glycol as fuels,at high temperature and short reaction time.The detonation soot was identified from X-ray powder diffraction (XRD) patterns,transmission electron microscope (TEM) and scanning electron microscopy (SEM) measurements.XRD analysis shows that nanoparticles of lithium and manganese oxides can be produced from detonation of slurry explosives due to fast quenching as well as appropriate detonation velocity,pressure and temperature.The results showed that the calcination temperature largely influenced crystalline phase and size of the powders.
