A novel pyrotechnic composition comprising nanostructured crystalline boron phosphide and oxidizer such as potassium nitrate wherein the crystalline boron phosphide is synthesized by a self-propagating high-temperature reaction. The nanostructured crystalline boron phosphide and oxidizer pyrotechnic composition unexpectedly emits smoke and green flame upon ignition.

A method for the manufacture of a composite fragmenting material having exothermic properties includes the steps of packing a mold with preformed metal fragments; filling interstitial spaces surrounding the metal fragments with a reactive metal powder to form a mixture; and then sintering the mixture at a temperature effective to both coat the metal fragments with the reactive metal powder and to bond the metal fragments together. In one embodiment the composite fragmenting material is formed into a nosecone for a warhead.

An in-situ process for synthesizing highly pyrophoric foam materials using metal and carbon precursors wherein the precursors serve as foaming and activating agents to disperse and lock nano-sized metal particles within a rigid porous carbon matrix. The resulting carbon matrix is also pyrophoric.

Provided herein is a symmetric amino triazine for use as a fuel and ignition source in chemically initiated illuminates or igniters. 3-amino-1,2,4-triazine act as a fuel and generates enough heat on exposure to as little as one drop of one hundred percent nitric acid to spontaneously ignite.

A plasticized pyrotechnic material can be easily portioned and formed or molded into a desired shape and burns at a high temperature (>2000 C.) but does not detonate. The plasticized pyrotechnic material may preferably include a combination of about 70-99% by weight of a pyrotechnic composition and about 1-30% by weight of a plasticizer composition comprising various low to mid molecular weight polyisobutylenes. The pyrotechnic material comprises inorganic oxidizers (e.g. metal oxides, oxohalide salts, nitrates, nitrites, chlorates/perchlorates) and metal or metal oxides powders mixed intimately. The plasticizer may include a small amount of a fluoropolymer, such as polytetrafluoroethylene (PTFE) and may also include up to 1-2% by weight of a processed oil, such as a mineral oil or motor oil. Some embodiments may also include a biocide precursor molecule.

A multicolor strobing pyrotechnic flare including a plurality of alternating pyrotechnic layers. The plurality of alternating pyrotechnic layers includes n pyrotechnic layers and the n pyrotechnic layers include m different pyrotechnic layer types, n is 2 to 2,000 and m is 2 to 2,000. The n pyrotechnic layers include a first pyrotechnic layer and a second pyrotechnic layer and the first pyrotechnic layer includes a first pyrotechnic compound and the second pyrotechnic layer includes a second pyrotechnic compound. Burning of the first pyrotechnic compound emits a first color and burning of the second pyrotechnic compound emits a second color and the first color and the second color are different.

A method for making a pyrotechnic composition in accordance with an embodiment of the present technology includes flowing metal powder, polytetrafluoroethylene powder, and binder powder in separate respective feed streams toward an extruder. The binder powder includes adhesive material and polytetrafluoroethylene anticaking material coating the adhesive material. The method further includes interspersing the metal powder, the binder powder, and the fluoropolymer powder to form a mixture. This mixture is then subjected to an extrusion process during which the anticaking material coating the adhesive material is disrupted. This releases the adhesive material to bind together the metal powder and the polytetrafluoroethylene powder in the extrudate. The powder mixture includes no solvent at any time between being formed and being extruded, yet the extrudate is well-mixed and cohesive.
