Nickel 5,5′-bistetrazole-1,1′-diolate dehydrate [Ni(BTO)(H2O)2],copper 5,5′-bistetrazole-1,1′-diolate dehydrate [Cu(BTO)(H2O)2] and cobalt 5,5′-bistetrazole-1,1′-diolate dehydrate [Co(BTO)(H2O)2] were prepared by complexation reaction of sodium 5,5′-bistetrazole-1,1′-diolate trihydrate and nickel nitrate,copper nitrate and cobalt chloride six hydrate,respectively.The crystal morphology of the complexes were studied by elementary analysis,FT-IR and SEM technology.The effect of three complexes of combustion catalyst on CL-20 and TKX-50 were studied by DSC experiments under linear temperature increase condition and isothermal.The results shown that three complexes had no affect on the thermal degradation of CL-20,but the melt transition peaks were postponed separately.Ni(BTO)(H2O)2 and Co(BTO)(H2O)2 had obviously affect on the thermal decomposition of TKX-50,and decreased the thermolysis peak.Ni(BTO)(H2O)2 had the most signicant catalytic effect on TKX-50.
