Abstract
Two newly synthesized versions of the insensitive high explosive (IHE) 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) were compared to two legacy explosives currently used by the Department of Energy. Except for thermal analysis, small-scale safety tests could not distinguish between the different synthetic routes. Morphologies of new TATBs were less faceted and more spherical. The particle size distribution of one new material was similar to legacy TATBs, but the other was very fine. Densities and submicron structure of the new TATBs were also significantly different from the legacy explosives and the densities of pressed pellets were lower. Recrystallization of both new TATBs from sulfolane produced nearly hexagonal platelets with improved density and thermal stability.
