Abstract
The present invention is a lead-free pyrotechnic composition comprising from about 60 percent by weight to about 80 percent by weight iodine pentoxide and from about 15 percent by weight to about 35 percent by weight of a solid-powder fuel. The solid-powder fuel may normally be selected from aluminum, magnesium, or a combination thereof. Depending upon the potential use for the lead-free pyrotechnic composition of the present invention, the composition may also include from about 4 to 10 percent by weight of a stabilizer that neutralizes any iodic acid formed by the iodine pentoxide, from about 3 to 5 percent by weight of a binder, or from about 5 to 15 percent by weight of a coloring agent. In a preferred embodiment of the invention, the aluminum will comprise aluminum flake having a size ranging from about nanometers to about 100 nanometers.
