Energetic co-particles have been proven effective in balancing high-energy and safety performance, which might be used as insensitive oxidizers solid propellants. In this work, the high temperature interactions between several aluminum (Al) powders presence of ammonium perchlorate (AP) studied. The are based on octogen (HMX) hexanitrohexaazaisowurtzitane (CL-20), with balanced energy content performance. They to combine Al AP form either binary or ternary systems. Their release rate during decomposition combustion fully evaluated. Due intimate contact components co-particles, binary/ternary systems exhibit superior reaction efficiency compared relevant mechanical mixtures same formulations. These novel energetic maximum two times higher pressurization rate, 10% heat explosion, 53.8% flame propagation much shorter ignition delay than corresponding normal mixtures. For both HMX- CL-20-based co-particle systems, median size condensed products (CCPs) is smaller those mixtures, Al2O3. This indicates that advantages improving particles by eliminating their agglomeration.
