The silver salt of 3,6-bis(1-H-1,2,3,4-tetrazole-5-amino)-1,2,4,5-tetrazine(BTATz)(Ag₂(BTATz)·2H₂O) was synthesized by two steps,and its structure was characterized by elemental analysis,X-ray fluorescence diffraction and FT-IR spectra. The thermal behavior of the compound was studied under non-isothermal conditions using DSC and TG-DTG methods,the result indicated that the thermal decomposition comprises of one endothermic and two exothermic stages,the non-isothermal decomposition reaction kinetics equation of the main exothermic stage can be expressed as:dα/dt=10^14.29×{3(1-α)[-ln(1-α)]^1/4/4} exp(-2.10 × 10⁴/T). The values of the self-accelerating decomposition temperature(T_SADT),critical temperatures of thermal explosion(T_b),thermal ignition temperature(T_TIT) and the adiabatic time-to-explosion(t_TIAD) for the compound were calculated as 517.10 K,580.12 K,531.00 K and 90.32 s,respectively. In addition,its thermal safety was evaluated.
