Lead free microdet electric detonators comprising a bridgewire having milled DBX-1 as a spot charge and unmilled DBX-1 as the intermediate material. Such improved microdet electric detonator is free of lead azide and lead styphnate, but with comparable stability, power and sensitivity to current lead-based M100 electric detonators.

Electric detonator with milled and unmilled DBX-1

A method of manufacture of the primary explosive material copper(I) 5-nitrotetazolate (DBX-1) by a synthesis starting with 5-aminotetrazolate (5-AT); wherein, the synthesis provides intermediates acid copper salt of 5-NT and sodium 5-nitrotetrazolate (NaNT) sodium 5-nitrotetrazolate (NaNT)&#x2014;that are both, free of any 5-aminotetrazolate (5-AT) starting material&#x2014;such that the subsequent production of the DBX-1 is not inhibited. Further, this method utilizes an internal filter within the reactor&#x2014;to minimize handling of explosively dangerous intermediates.

Synthesis of copper(I) 5-nitrotetrazolate

A method for preparing an insensitive bis(2,2-dinitropropyl)nitramine (BDNPN) as a fine powder which exhibits desirable insensitive munitions (IM) characteristics for use alone or compounded with other energetic materials such as RDX.

Preparation of insensitive bis(2,2,-dinitropropyl) nitramine (BDNPN)

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.

High explosive fills for very small volume applications

High explosive coatings and inks suitable for use in micro-electronic initiators for micro-electro-mechanical mechanisms used as safe and arm devices, are prepared from coating compositions of crystalline energetic materials and applied using various methods. These methods include wiping and spraying, as well as, pressure applications using a syringe or the like, and application of thick film ink to write specified patterns on a selected surface. A volatile mobile phase may be added to the coating composition to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the selected surface.

Method for producing and using high explosive material

A detonator for a hand grenade fuze comprises a detonator case; a slider that is transversely reciprocable in the detonator case from an unarmed position to an armed position, the slider including a longitudinal through-hole filled with a primary explosive; a spring that biases the slider to the unarmed position; an arming mechanism attached to the slider, the arming mechanism comprising a shape memory alloy; an explosive lead disposed below the slider; and a booster charge disposed below the explosive lead.

The present invention discloses a process for the on-demand production of small quantities of lead azide. First, a metered quantity of sodium azide solution and a metered quantity of a solution of a lead salt sufficient to react with the sodium azide are introduced into a T-mixer or Y-mixer. Then, the sodium azide and lead salt solutions are conveyed into a static mixer and the azide and lead compounds are permitted to react together, forming insoluble crystals of lead azide as a slurry in an aqueous medium. The lead azide crystals are then separated from the aqueous medium. The process is carried out within an explosion-proof chamber.
