ABSTRACT
A new 1:1 cocrystal explosive composed of 2,4,6,8,10,12-hexanitrohexaazaiso-wurtzitane (CL-20) and 1,4-dinitroimidazole (1,4-DNI) was synthesized through cocrystallization by slow solvent evaporation. The has a crystal density 1.922 g/cm3 at 296 K belongs to the orthorhombic system with P212121 space group. properties including thermal stability, impact sensitivity, detonation performances were studied. DSC test shows that melting point 115 °C decomposition temperature 253 °C, suggesting an excellent stability. Furthermore, exhibits energy 50% ignition probability 10 J, showing substantial reduction in sensitivity compared pure CL-20 HMX. Besides, predicted velocity pressure are 9242 m/s 39.01 GPa, respectively, which similar those Therefore, CL-20/1,4-DNI may be attractive high low and, thus, act as promising candidate instead HMX for vulnerability formulations future.
