    Soild-state decomposition mechanisms with conversion extent for ammonium percholorate catalyzed with nanothermite particles

    Colloidal ferric oxide/aluminum nanothermite mixture was incorporated into ammonium percholorate (AP). Nanothermite particles experienced an increase in AP decomposition enthalpy by 120% using DSC. Decompositi...
