Study on explosive properties of BCHMX

摘要

A bicyclic nitramine cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazoIe (bicyclo-HMX, BCHMX) is an energetic material with a heat of explosion and a relative explosive strength exceeding that of β-HMX. Although a lot of research was done to study the performance of compositions with different explosives and to analyse the effect of various polymeric matrices, there is a lack of reported explosive properties of BCHMX in the literature. In order to change that, the material was synthesized from easily available substrates, recrystallized, and phlegmatized with Viton. The morphology of crystals was studied with optical microscopy. Afterwards, it was pressed and used in a form of cylindrical charges. Amongst the test methods which were applied in the study, we can name the determination of blast wave parameters, critical diameter, and the gap test. The experiments were also done for phlegmatized RDX and HMX and the results were compared.
