Abstract
High explosives suitable for filling very small volume loading holes in micro-electric initiators for micro-electro-mechanical mechanisms, used as safe and arm devices, are prepared from slurries of crystalline energetic materials including organic liquid and applied using various methods. These methods include swipe loading, pressure loading and syringe loading. The organic liquid serves as a volatile mobile phase in the slurry so as to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the loading hole.
