Abstract: The invention consists of a class of high energy explosive yield enhancers reated through the use of microencapsulation techniques. The microcapsules consist of combinations of highly reactive oxidizers that are encapsulated in either passivated inorganic fuels or inert materials and inorganic fuels. Depending on the application, the availability of the various oxidizers and fuels within the microcapsules can be customized to increase the explosive yield or modify other characteristics of high explosives. The microcapsules prevent premature reaction of the component oxidizers and inorganic fuel to allow their use in munitions and propellant applications. The physical stability of the microcapsules, in combination with epoxies, plastics, and composites, also permits microcapsules to be included in warhead structural components.
