Abstract

The synthesis of super-reactive metastable intermolecular composite (MIC) formulation of AL/KMnO4 was described using nanoscale energetic materials. Reaction-rate measurements were performed in terms of pressurization rate under confined combustion of the MIC. The synthesis of KMnO4 nanopaticles was done by an aerosol-phase spray-drying method, and pressurization-rate performance of a MIC in the form of a loose powder composed of Al/KMnO4 nanoparticles. It was found that a strong correlation existed between the pressurization rates for several MIC combinations and the fraction of reactive oxygen present in the combustion product.
