The thermal analysis technique was used to rapidly evaluate the compatibility of explosives with contacted materials. The three kinetic parameters viz. activation energy E, reaction order n and pre‐exponential factor A were calculated from three characteristic temperatures of a single DTA curve. The compatibility was evaluated from the four parameters E, n and the characteristic temperatures T m (peak maximum) and T o (decomposition starting point on the DTA curve). The results are compared to those obtained from the gasometric method.
