Abstract
The production technique of mechanoactivated energetic composition (MAEC) based on ammonium perchlorate (AP) and aluminum has been developed. For preparation of the mixtures, regular powders of AP (20–100 μm) and Al powders—pyrotechnic powder PP-2 (flake particles 50–200 μm by thickness 2–5 μm) and Al(8) (average size of particles ~280 nm)—were used. The components were mixed and activated in an Activator-2SL planetary ball mill (JSC “Activator,” Novosibirsk) with steel balls and drums and with water cooling. The optimum conditions of mechanical activation were found so that the maximum homogenization of the mixture was provided in the absence of the reaction between reagents. The structure of MAEC was studied by X-ray diffraction analysis and scanning electron microscopy. The results of research of explosive properties (deflagration to detonation transition (DDT) in Al/AP loose-packed charges, dependence of detonation velocity (DV) on density for the pressed charges, and mechanical sensitivity) have been received.
