The Effects of Impurities and Additives on the Growth of Polycrystalline TNT

Abstract

Growth of polycrystalline TNT on thermal cycling depends upon the presence of impurities in the TNT. Growth increases with the concentrations of 2,4-dinitrotoluene and 2,3,4-trinitroluene individually (these materials are major impurities in commercial TNT), and these materials have a synergistic effect on growth when they are present together. On the other hand paraffin wax and beeswax, commonly added as desensitisers to TNT-based compositions, have no effect on the growth process. Finally the presence of anthracene and 11- nitronaphthalene, additives recommended to reduce exudation and/or cracking in commercial TNT charges, increases growth in polycrystalline TNT. These results are fully in accord with the mechanism proposed previously to account for the growth process.
