Studies on the Thermal Behaviors of Hexogen, Ammonium Perchlorate and Their Mixtures by TG-DSC

In order to study the effect of the oxidizer ammonium perchlorate (AP) on the energy release of composite energetic materials, the thermal decomposition of AP with different particle size, Hexogen (RDX), and their mixtures were studied by means of thermogravimetry-differential scanning calorimetry (TG-DSC). The results showed that RDX had one weight loss step and there were two weight loss steps for AP and the mixture of AP and RDX. We can also conclude that RDX and AP accelerate the thermal decomposition of each other and the change of particle size of AP has no effect on this acceleration.
