A method for estimating critical temperature (Tb) of thermal explosion for energetic materials was derived from Semenov's [9] thermal explosion theory and the nonisothermal kinetic equation [image omitted] based on Berthelot's expression using reasonable hypotheses. The final formula is [image omitted], which is simple. We can easily obtain the onset temperature (Tei) from the nonisothermal DSC curves, the value of Te0 from the equation [image omitted], the values of b from the equation [image omitted], and then calculate the value of Tb. The result obtained with this method coincides completely with the value of Tb obtained by Zhang et al.'s [4] method.
