COMPOSITE OXIDES FROM EMULSION EXPLOSIVES
Some performance of emulsion explosives containing epispastic polystyrenewere studied experimentally and theoretically.The detonation products werecharacterized by scanning electron microscopy.Powder X-ray diffraction andtransmission electron microscopy were used to characterize the products.Themethodology assumes that the heat of detonation of an explosive compound ofcomposition CaHhNcOdLieZnf can be approximated as the difference between theheats of formation of the detonation products and that of the explosive,divided bythe formula weight of the explosive.For the calculations in which the first set ofdecomposition products is assumed,predicted temperatures of detonation ofemulsion explosives with the product H2O in the gas phase have a deviation of 446K from results with the product H2O in the liquid state.Fine-particle lithium andzinc oxides have been prepared by the detonation of emulsion explosives of themetal nitrates,M (NO3) x (M = Li,Zn) as oxidizers and paraffine as fuels,at hightemperature and short reaction time.Free metal atoms are first released with thedecomposition of explosives,and then theses metal and oxygen atoms arerearranged,coagulated and finally crystallized into lithium and zinc oxides duringthe expansion of detonation process.Lithium and zinc oxides with a fine sphericalmorphology different from that of the normal product is formed after detonationwave treatment due to the very high quenching rate.It might also provide a cheaplarge-scale synthesis method.
