Recent focus on Insensitive Munitions has directed research towards ingredients and formulations that can be used to produce insensitive explosives and ordnance, with efforts largely concentrated on main charge fills. Another key component of any munition is the booster system, which is required to reliably initiate the main charge. This requires attention as it is often the most sensitive component and unintentional initiation could lead to a violent reaction from the munition. 1,1-Diamino-2,2-dinitroethylene FOX-7 is a recently developed high explosive ingredient with significant potential for application in a range of high performance, insensitive explosive compositions. The performance of FOX-7 is close to that of the benchmark nitramine explosive RDX and sensitiveness and hazards testing of FOX-7 have provided favourable results. Previous studies utilising FOX-7 have demonstrated its potential for insensitive booster formulations, easily meeting basic requirements for this application. This report details further testing of the performance and sensitivity of FOX-7 booster formulations. Also included are particle processing techniques using ultrasound, designed to optimise FOX-7 crystal size and morphology to improve booster formulations, and results from these experiments.
