Studies on Thermal Decomposition of Energetic Materials by Dynamic Vacuum Stability Test Method

摘要：

Dynamic Vacuum Stability Test (DVST) method based on the manometry principle of VST can track and test thermal decomposition of energetic materials real-time, continuously and directly as a new thermal analysis method. The thermal decomposition of TATB, RDX, HMX and CL-20 were investigated by DVST. Activation energy (E) and pre-exponential factor (A) at 100℃ can be obtained through the non-isothermal DVST method, while the reaction model (G(α)) and reaction rate constant (k) of the samples were obtained by the isothermal DVST method. Futhermore, DVST can determine the thermal stability of the energetic materials more accurately than traditional VST.
