AB  - Thermal decomposition of a highly thermostable explosive dihydroxylammonium 
      2,4,8,10-tetranitro-benzopyrido-1,3a,6,6a-tetraazapentalene (BPTAP) was studied 
      using conventional thermal analysis techniques (Thermal Gravimetric Analysis and 
      Differential Scanning Calorimetry). To obtain more comprehensive insight into the 
      kinetics mechanism of BPTAP decomposition, thermoanalytical experiments were 
      performed under non-hermetic and hermetic conditions. Several widely used 
      thermoanalytical data processing techniques based on model-free kinetics 
      (Flynn-Wall-Ozawa, Kissinger, Freidman, numerical optimization) were studied and 
      compared. Furthermore, to fully understand the thermal safety property of BPTAP, 
      the kinetic model and the kinetic parameters were evaluated based on the 
      non-isothermal DSC data by using a non-linear optimization method. The kinetic 
      models of thermal decomposition of BPTAP under non-hermetic and hermetic 
      conditions were different, which were identified as the generalized autocatalysis 
      reaction and two parallel generalized autocatalysis reactions, respectively. On 
      the basis of the aforementioned study, two important safety parameters including 
      the time to maximum rate under adiabatic conditions and self-accelerating 
      decomposition temperature for BPTAP in DEWAR were calculated and discussed.
