Safety Explosive for Ceramic Oxides
This investigation promotes the design of safety emulsion explosives and the development of detonation theory on a micro scale. As the total composition of oxidizing and reducing elements of the reactants leave related to the thermo chemistry of the system, the computational details of predicting the temperatures of detonation were introduced. It was found that a significant improvement was achieved in the emulsion explosives with an aquiferous system. An improvement in the detonation synthesis of nano-lithium and zinc oxides is due to the formation of an activated matrix of the metal nitrates oxidizer with the. corresponding fuel. Temperatures of detonation of emulsion explosives and explosive formulations are predicted using thermo chemistry information. The methodology assumes that the heat of detonation of an explosive compound of composition CaHbNcOdLieZnf 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 temperatures of detonation of emulsion explosives with the product H20 in the gas phase have a deviation of 413.66 K from results with the product H2O in the liquid state. Fine-particle lithium and zinc oxides have been prepared by the detonation of emulsion explosives of the metal nitrates, M (NO3) x (M = Li, Zn) as oxidizers and pataffine as fuels, at high temperature and short reaction time. The detonation products were identified from X-ray powder diffraction (XRD) pattern, and transmission electron microscopy (TEM) measurements. XRD analysis shows that nanoparticles of lithium and zinc oxides can be produced from detonation of emulsion explosives due to fast quenching as well as appropriate detonation velocity and temperature.
