Standardizing differential scanning calorimetry (DSC) thermal decomposition temperatures at various heating rates of an energetic material as a threshold one
Differential scanning calorimetry (DSC) test is capable of providing comprehensive data of peak temperature (Tp, K) and onset temperature (To, K) at various heating rates (β) and widely applied in the thermal safety assessment of energetic materials (EMs). However, Tp and To (Tp/o) are variable, dep...

| Summary: | Differential scanning calorimetry (DSC) test is capable of providing comprehensive data of peak temperature (Tp, K) and onset temperature (To, K) at various heating rates (β) and widely applied in the thermal safety assessment of energetic materials (EMs). However, Tp and To (Tp/o) are variable, depending on β, making inconvenience and confusion in thermal stability of different EMs, in particular, in the case of testing conditions absent. This study aims to standardize Tp/o at various β to Tp/o,β→0 as a threshold temperature of thermal decomposition. It is confirmed that Pow2P2 (two-parameter power function) is feasible to fit the Tp/o−β relationship by any two experimental points, and extrapolate Tp/o,β→0. Thereby, Tp/o,β→0, as a single value of DSC test of one EM, benefits for thermal stability study. |
