Abstract

Titanium/blackpowder compositions have been involved in a number of ignition incidents during consolidation. We report the results of a systematic study to investigate the effects of the particle size and proportion of titanium on the mechanical sensitiveness of such mixtures. Our results indicate that the compositions are sensitive to both impact and friction stimuli and that the forms of the dependence on titanium content are different. Mixtures of blackpowder with 20%–30% titanium have been shown to be particularly friction sensitive. We have also found that the sensitiveness of titanium/blackpowder compositions to mechanical forces is independent of the particle size of titanium over the range investigated in this study.

## Abstract An explosion occurred recently during the operation of a grinder that had been used to process potassium chlorate and then thiourea. As part of our investigation of this accident we determined the mechanical sensitiveness of mixtures containing these components and showed that they can
