Abstract: 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.

Abstract: The present invention is directed to preparing pyrophoric foam granules having a specific infrared signature comprising the steps of (a) mixing a composition comprising a metal salt, carbohydrate, and wetting agent into a homogenous paste, (b) extruding the composition into strands, (c) cutting or spheronizing the strands into a predetermined size or length based on a specific thermal or infrared response to produce pyrophoric foam granules and (d) activating the granules by heating the composition at elevated temperatures under an inert or reducing atmosphere until the matrix is carbonized and the metal salt is reduced.

Abstract: The present invention is directed to a device for dispensing pyrophoric decoy particulates where the device is comprised of at least one payload vessel having a structural wall that forms a cavity for housing a plurality of pyrophoric particles. The structural wall has at least one opening to facilitate dispersal of the pyrophoric particles. The payload vessels are inserted inside a tubular sleeve and hermetically sealed inside the sleeve. Within the sleeve the at least one payload vessel is also in direct contact with an expulsion assembly that upon activation pushes the payload vessels and its pyrophoric contents out of the sleeve to react with the air.

Abstract: 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.

Abstract: A simplified method for synthesizing boron phosphide at high yields. The method requires mixing of boron phosphate and magnesium metal without diluents into a homogenous mixture, loosely packing the mixture at less than 20,000 psi and igniting the mixture using an energy input that is not greater than 20% of the reaction energy output to create a self-propagating high-temperature reaction wherein the boron phosphate and magnesium metal is completely burned during the reaction to synthesize boron phosphide at high yields.
