Low Temperature Explosion for Nanometer Active Materials


Article Preview

This paper describes a new method for prediction of the Chapman–Jouguet detonation parameters of CaHbNcOdLieMnf explosives for mixture of some of low temperature explosion explosives at 0 = 1000 kg/m3. Explosion temperatures of water-gel explosives and explosive formulations are predicted using thermochemistry information. The methodology assumes that the heat of detonation of an explosive compound of products composition H2O–CO2–CO–Li2O–MnO2–Mn2O3 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 explosion of water-gel explosives with the product H2O in the gas phase have a deviation of 153.29 K from results with the product H2O in the liquid state. Lithium and manganese oxides have been prepared by the explosion of water-gel explosives of the metal nitrates, M (NO3) x (M = Li, Mn) as oxidizers and glycol as fuels, at relative low temperature. We have also used the Dulong-Petit’s values of the specific heat for liquid phase H2O. Lithium manganese oxide powders with chrysanthemum-like morphology secondary particles, but with smaller primary particles of diameters from 5 to 30 nm and a variety of morphologies were found. The oxides produced by this cheap method affirmed the validity of explosion synthesis of nano-size materials for lithium ion batteries.
