Abstract:   (2532 Views)
Preparation of micron and nano sized ammonium perchlorate (AP) particles in propellant formulation is required for access high burning rate propellants. The decomposition and burning rate of AP particles are mainly affected by decreasing the particle size, which can decrease the decomposition temperature, and increase burning rate.  AP particles at the micro and nano-scales, have a great influence on the burning rate of composite solid propellants. By decrease in particle size of AP, surface area and burning rate of produced propellant are increased. Furthermore, tensile strength and elastic modulus of the propellants in the presence of superfine AP increased. Conventional methods for preparation of fine AP such as ball-milling, sol-gel, liquid antisolvent crystallization, freeze drying, and spray drying methods are used. In this paper, the advantages and limitations of various methods of superfine AP production are investigated.
