| Summary: | Title screen Metal powders (mainly aluminum), due to their high energy density, are important fuels for propulsion systems, material synthesis, and energetic materials. However, the use of aluminum is complicated by the fact that during storage and combustion on the surface of the particles an inert oxide layer is formed, which prevents the access of an oxidizer and increases the ignition and burning times of particles. Prospective solution to the problem of increasing the efficiency of metal fuel combustion is the complete or partial replacement of aluminum by energy-intensive components or Al/Mg alloys in energetic materials. This chapter presents the thermal analysis data, the ignition parameters, the combustion, and agglomeration characteristics for the propellants based on ammonium perchlorate, butadiene rubber, and Alex, Alex/Fe, Alex/B ultra-fine powders. The experimental results showed the reduction of the ignition delay time and increase of the burning rate for the EM sample containing Alex/Fe ultra-fine powder in comparison with the Al-based energetic material. The presence of amorphous boron in the bimetal fuel of EM significantly increases the agglomeration of condensed combustion products and practically maintains the burning rate of propellant unchanged.
