Critical temperature(T b ) of thermal explosion for energetic materials is estimated from Semenov’s thermal explosion theory and the non-isothermal kinetic equation dα/dt=A 0 exp(bT)[1+(T–T 0 )b]f(α) deduced via reasonable hypotheses, where T 0 is the initial point of the deviation from the baseline of DSC curve. The final formula is (T b –T e0 ){1+1/[1+( T b –T 00 )b]}=1. We can easily obtain the initial temperature(T 0i ) and onset temperature(T ei ) from the non-isothermal DSC curves, the values of T 00 and T e0 from the equation T 0i or ei =T 00 or e0 +α 1 β i +α 2 β i2 +…+α L–2 β iL –2 , i=1,2,…,L, the value of b from the equation: ln[β i /(T ei –T 0i )]=ln[A 0 /G(α)]+bT ei , so as to calculate the value of T b . The result obtained with this method coincides completely with the value of T b obtained by Hu-Yang-Liang-Wu method.
Critical temperature (T b) of thermal explosion for energetic materials is estimated from Semenov’s thermal explosion theory and the non-isothermal kinetic equation dα / dt = A 0 exp (bT) [1+ (T-T 0) b] f The final formula is (T b -T e0) {1 + 1 / [1+ (T b -T 00) b ]} = 1. We can easily obtain the initial temperature (T 0i) and onset temperature (T ei) from the non-isothermal DSC curves, the values of T 00 and T e0 from the equation T 0i or ei = T 00 or e0 + α 1 β i + α 2 β i2 + ... + α L-2 β iL -2, i = 1,2, ..., L, the value of b from the equation: ln [β i / T 0i) = ln [A 0 / G (α)] + bT ei, so as to calculate the value of T b. The result obtained with this method coincides completely with the value of T b obtained by Hu-Yang-Liang -Wu method.
