In this work, new cyclic nitramine named cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX) was premixed with insensitive explosives (3-nitro-1,2,4-triazol-5-one, NTO and1,1-diamino-2,2-dinitroethene, FOX) and with two cyclic nitramines (1,3,5-trinitro-1,3,5-triazinane, RDXand, 1,3,5,7-tetranitro-1,3,5,7-tetrazocane, HMX) and bonded by polydimethyl-siloxane (PDMS) binder.Impact and friction sensitivities were evaluated. Detonation velocity was measured and the detonationcharacteristics were calculated by EXPLO 5 thermodynamic code. Relative explosive strength wasdetermined by using the ballistic mortar test. The results showed a great positive influence on the sensitivityof BCHMX due to the addition of the insensitive explosive (NTO, FOX-7) however the performance wasdecreased. On the other side, mixing the nitramines improved the performance with reduction of BCHMXsensitivity. PDMS binder succeed to decrease the sensitivity of all the studied mixtures.

AbstractFree-radical thermal and photochemical decomposition products of ammonium dinitramide (ADN), an acyclic nitramine, are compared to that of cyclic nitramines (RDX, HMX, and HNIW) and to ammonium perchlorate (AP). Photochemical formation of NO2 from uvphotolysis of ADN at 77 K is found to follow first-order kinetics; whereas, zero-order NO2 formation is observed from the cyclic nitramines under the conditions of this experiment. Mechanisms are suggested for ADN decomposition. A general trend of cyclic nitramines to thermally decompose forming nitroxide radicals is supported by 15N-ring-labeled HNIW results. ADN thermally decomposes at 19° C to form free-radical reaction products in solution with tetrahydrothiophene-1,1-dioxide.
