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.
