Non-isothermal Studies on the Thermal Decomposition of C4 Explosive Using the TG/DTA Technique

摘要: The thermal behaviour of energetic materials is very important for their safe production, storage, handling and even demilitarization. In this work, the decomposition kinetics conventional C4 plastic explosive has been studied experimentally by a non-isothermal thermogravimetric (TG)/differential analysis (DTA) technique at different heating rates (2, 4, 6 8 °C·min-1). kinetic triplet activation energy, frequency factor model compound evaluated via model-fitting model-free methods. results show single process C4, with integral function (g(α)) [(1−α)-1/3 −1]2 differential (f(α)) [(1−α)2/3(3α−3)/2(1−α)1/3−2], indicating 3-dimensional diffusion mechanism. addition, Ea values 207.1 ± 17.3, 241 kJ·mol-1, using isoconversional modified Kissinger-Akahira-Sunose (KAS) Kissinger method, respectively, were obtained conversion interval 0.3-0.7. matrix shows significant effect on energy distribution pure RDX.
