Surface Chemistry Promoting Energetic Material Combustion
Abstract
The main goal is to enhance aluminum reactivity through understanding surface exothermic kinetics that facilitate combustion. To accomplish this goal, this project examines surface reactions of aluminum particles with various halogen containing oxidizers (i.e., fluorine and iodine) as well as ignition and combustion properties affected by these surface reactions. The surface reactions are triggered by a halogen species, such as fluorine in fluoropolymers or iodine or chlorine oxidizing salts or binders. The objective is to understand the reaction kinetics of halogens with the alumina passivation shell surrounding aluminum particles, then use this understanding to design formulations that show greater reactivity. Our focus is on three areas of research including: (1) developing mechanistic understanding of reaction pathways that promote surface reactions; (2) analyzing and modeling Al combustion for ignition and energy propagation; and, (3) synthesizing and characterizing novel formulations that capitalize on the surface reactions.
