  • DEMILITARIZATION OF WAX DESENSITIZED EXPLOSIVE PROJECTILES
    Publication number: 20120227877
    Abstract: A method for demilitarizing projectiles, typically military projectiles, containing a class of energetic materials known as Composition A which are wax desensitized materials. The projectiles are opened to expose the wax desensitized energetic material, which is then removed from the projectile by fluid jet technology. The wax component is separated from the energetic particles only to a degree that will leave an effective amount of desensitizing coating of wax remaining on the particles.
