In view of the volatile quality of 2,4,6-triazido-1,3,5-triazine (TAT) after melting, a special high-pressure hermetic crucible was used to analyze the compound's thermal decomposition behaviors. The complete exothermic decomposition process of TAT was obtained, and the extrapolated onset temperature, peak temperature, and decomposition enthalpy at a heating rate of 10.0 °C/min were measured as 195.1 °C, 221.4 °C and -3753.0 J/g, respectively. The hermetic thermal decomposition kinetic equation was thus obtained. The self-accelerating decomposition temperature and critical temperature of thermal explosion for TAT were 173.7 °C and 186.6 °C, respectively. The specific heat capacity of TAT was determined, and the molar heat capacity was 234.67 J/(mol · K) at 298.15 K. It can be observed that TAT possesses a high thermal decomposition temperature and a drastic heat release.
