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: Disclosed herein are pyrophoric composite materials comprising nanoporous pyrophoric alpha iron nanoparticles dispersed in a ceramic matrix for use as aerial decoys. The composite material is prepared using tape casting methods to produce a thin film. The iron precursor in the film is then activated by reduction under a hydrogen atmosphere. The composite nanoporous pyrophoric alpha iron nanoparticles and ceramic material is an improvement over current pyrophoric decoys as it eliminates the use of harmful chemicals and the need for a substrate to support the composite.
