Description

A new energetic Ca(H2O)6·(HZTO·2H2O)2 was crystallized in the monoclinic space group C2/c, and its thermal characteristics and kinetics were studied by differential scanning calorimetry (DSC) and accelerating rate calorimetry (ARC). DSC measurements showed one endothermic peak and one exothermic peak with decomposition occurring at 286.8, 290.5, 296.5, and 303.2 °C at different heating rates (2.5, 5, 10, and 20 °C min−1). The critical temperature of thermal explosion (Tb) and kinetics parameters were calculated; the results show that Ca(HZTO·2H2O)2·6H2O is stable below 273.1 °C. The thermal behavior of Ca(H2O)6·(HZTO·2H2O)2 under adiabatic condition was studied by ARC: The onset temperature was 185.7 °C, and the thermal decomposition ended at 228.2 °C within the time span of 458.1 min. In addition, thermokinetic parameters such as the activation energy Ea and pre-exponential factor A under adiabatic condition were also obtained.
