摘要
Ammonium perchlorate (AP)/HMX co-crystal with dual catalytic effect was developed. Proper integration of AP particles into the HMX matrix was verified with the evolution of novel crystalline structure. AP/HMX co-crystal demonstrated an increase in HMX decomposition enthalpy by + 57.5%. HMX demonstrated activation energy of 343.2 and 354.4 kJ/mol using Kissinger and KAS models, respectively. AP/HMX co-crystal demonstrated a decrease in HMX activation energy by −75% and −76%, correspondingly. AP could act as an active point with the release of reactive gases that could boost HMX decomposition. HMX experienced a catalytic effect with the disappearance of AP endothermic phase transition.
