Effects of Sn-containing intermetallic compounds on the thermal decomposition and ignition properties of RDX and TKX-50

An Overview on Synthesis, Explosion, Catalysis, Modification, and Application of Dihydroxylammonium 5,5′-Bistetrazole-1,1′-diolate (TKX-50)

“…When the metal is combined with other metals to form a polymetallic alloy structure, the resulting alloy phase has better high-temperature structural stability, efficient catalytic activity, and better redox activity than a single metal. Zhao et al 101 synthesized three intermetallic compounds (Sn−Cu), Sn− cobalt (Sn−Co), and Sn−nickel (Sn−Ni) by hydrothermal synthesis. When Sn−Cu, Sn−Ni, and Sn−Co intermetallic catalysts were mixed with TKX-50 to measure DSC, the peak exothermic decomposition temperatures of TKX-50 waswere reduced by 11.9, 6.6, and 1.5 °C, respectively (Figure 18).…”

“…Research found that the introduction of metal in the thermal decomposition process of TKX-50 can improve its thermal decomposition performance. − Ju et al studied the decomposition process of the TKX-50 molecule on the surface of Al (111) by using the DFT method, to explore the decomposition mechanism of the pyrolysis of TKX-50 by Al. The activation energy of TKX-50/Al is lower than that of TKX-50 due to the formation of N–Al, O–Al, and OH–Al bonds on the surface of Al.…”
