Abstract
The thermal decomposition characteristic of HMX influenced by the addition of aluminum, nickel, copper with different particle size (general and nano-meter) are studied by PDSC and TG. The results showed that nano copper had the greatest influence on the condensed-phase decomposition characteristic of HMX among the metal powders. Such catalysis effect will be weakened by the decrease of the content of metal powder or the increase of system pressure. Based on the kinetics result inferred from the isothermal DSC experiment, the mechanics of such influence are attributed to the efficacy of catalysis effect, secondary effect and reaction site effect.
