A Study of a Set of Pyrotechnic Strobe Compositions Based on Ammonium Perchlorate

Richard Harrison

Abstract:  The subject of this study is a set pyrotechnic strobe compositions, containing ammonium perchlorate, a magnesium-aluminum alloy, barium sulfate and potassium dichromate, together with a small amount of nitrocellulose to act as a binder. Despite the fact that compositions of this type have been previously studied in some detail, there is still no consensus about the reaction mechanisms that are likely to be involved.

An examination of temperature profiles obtained from freely reacting samples provides support for earlier ideas about the nature of the flash reaction, but indicates that the principal reaction in the smolder phase is likely to be different from those that have previously been proposed.
