    The thermal decomposition kinetics of hexanitrohexaazaisowurtzitane/ ammonium perchlorate (HNIW/AP) have been investigated by thermogravimetry- differential scanning calorimetry-mass spectrometry (TG-DSC-MS) simultaneous analysis. TG showed that there were three weight loss processes for the thermal decomposition of the HNIW/AP mixture. The first was ascribed mainly to the thermal decomposition of HNIW, while the second and third were assigned to that of AP. The presence of AP has little effect on the thermal decomposition process of the HNIW component. The apparent activation energy of the thermal decomposition of the HNIW component, calculated by the Kissinger method, was little changed compared to that of neat HNIW. The addition of HNIW to AP caused the onset and end temperatures of the thermal decomposition to be decreased and the decomposition process to be shortened. The high-temperature and low- temperature decomposition processes of AP became blurred in the presence of HNIW, and this was supported by the MS results.

    Al/CuO/PG nanocomposites were investigated in this paper as potential catalysts for the thermal decomposition of ammonium perchlorate (AP), where the high temperature decomposition of AP decreases from 424.4°C to 312.3°C, showing its strong catalytic activity on the thermal decomposition of ammonium perchlorate. In addition, the more the catalyst was added, the more the high-temperature decomposition temperature of AP decreased.
