摘要

TNO Prins Maurits Laboratory has actively followed and contributed to the research on the development of insensitive munitions(IM).One of the initial research topics at TNO focused on the improvement of the shape of RDX crystals and its relation to the shock sensitivity.The variation of crystal shape has been studied by crystallization from different solvents and/or by post-treatment of the crystals.The role of the mean particle size on shock sensitivity was also included in these analyses.The decrease in shock sensitivity is even more pronounced when controlling the internal quality of crystals.In the meantime research has shifted to other energetic materials as well - in particular HMX and CL-20 -in this way revealing step by step the important physicochemical parameters which play a role in determining the shock sensitivity of formulations containing these types of nitramines.Various characterization techniques,to determine the internal and external quality of crystals will be discussed,and their relation to shock sensitivity in PBXs will be shown.Two different grades of I-RDX have been subjected to different characterization tests.The objective is to gain more understanding about which of the physicochemical parameters enables one to discriminate between a reduced sensitivity RDX and normal RDX.
