Insensitive high explosives: IV. Nitroguanidine – Initiation & detonation

摘要: Abstract This paper reviews the detonative properties of low bulk density (LBD), high (HBD) Nitroguanidine (NGu)(1), CAS-No: [556-88-7] and 82 explosive formulations based on NGu reported in public domain. To rank performance those they are compared with 15 reference compositions containing both standard explosives such as octogen (HMX)(2), hexogen (RDX)(3), pentaerythritol tetranitrate (PETN)(4), 2,4,6-trinitrotoluene (TNT)(5) well insensitive 3-nitro-1,2,4-triazolone (NTO)(6), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB)(7), 1,1-diamino-2,2-dinitroethylene (FOX-7)(8) N-Guanylurea dinitramide (FOX 12)(9). superior to FOX-12 or TATB a close match FOX-7 explosives, latter just having higher Gurney Energies (∼10%) slightly detonation pressure (+2%). even reach up 78% pressure, 82% energy 95% velocity HMX. LBD-NGu dissolves many melt cast eutectics forming dense charges thereby eliminating need for costly High Bulk Density NGu. at rock bottom sensitiveness among all above-mentioned which contributes safety these formulations.
