Explanation

A compound with a cage shaped molecular structure and containing multiple nitro groups. It is a high energy density materials (HEDM), such as polynitropolyhedral alkanes, polycyclic cage ammonium nitrate, etc. Symmetric structure, high density, excellent explosion performance. The synthesized polynitropolyhedral alkanes include 1,4-dinitrocubane, 1,3,5-nitrcubane, 1,3,5.7 tetranitrocubane, hexanitrocubane, tetranitrodihomocubane, tetranitrodihomopentagonane, hexanitro-Cs-trihomocubane, hexanitro-Ds-trihomocubane, tetranitroadamantane, etc. The United States has designed three polycyclic caged nitramine, namely, hexanitrohexaazaadamantane, hexanitrohexaazawurzane and HNIW. The density of the three nitramine can reach more than 2.0g/cm3 (10% higher than that of Octogen), the detonation pressure is 9.4-9.5km/s (4% higher than that of Octogen), and the detonation pressure is 42.0-43.OGPa (8% higher than that of Octogen). Caged polynitrocompound can be used in high energy density propellants, underwater charges, high penetration cone charges and nuclear weapon charges, and will have a significant impact on the performance of weapon systems.
