Combustion behavior and physico-chemical properties of dihydroxylammonium 5,5 '-bistetrazole-1,1 '-diolate (TKX-50)

摘要: Abstract The physico-chemical characterization (thermal decomposition under non- and isothermal conditions, enthalpy of formation, burning behavior flame structure) a new explosive dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate is detailed. Combustion studies have shown that TKX-50 burns slightly faster than HMX approaches the rate CL-20. combustion has been to obey mechanism with leading reaction in condensed phase. rates both solid liquid phases proved be higher corresponding RDX. Decomposition determined by free hydroxylamine formed dissociation salt. An intermediate product ammonium salt 5,5′-bis(2-hydroxytetrazole), which further decomposes second stage at elevated temperatures. formation measured help bomb calorimetry, however resulting value quite different from reported earlier.
