Boron-containing, green light emitting pyrotechnic compositions that advantageously do not include barium, perchlorate or chlorinated organic compounds.

Green light emitting pyrotechnic compositions

An infrared illuminating composition comprising approximately 70 weight % of an oxidant evidencing strong emission in the NIR region selected from the group consisting of potassium nitrate, cesium nitrate and mixtures thereof; 9 weight % of a metallic fuel evidencing low visible light emission, 4 weight % of an epoxy resin binder, 16 weight % of a NIR light enhancer and 1% by weight of an additive selected from the group consisting of a double base propellant material, a triple base propellant material and mixtures thereof.

Storage-stable metal-fueled pyrotechnics and methods for manufacturing such compositions are provided. These are manufactured by granulating a mixture of liquid cyclohexane, powdered metal fuel, optional Teflon&reg; powder, and at least one ethylene and vinyl acetate co-polymer, together to form a storage stable powdered metal fuel effectively coated with ethylene and vinyl acetate co-polymer. This provides pyrotechnics with superior resistance to degradation induced by atmospheric moisture, and having other improved properties. The powdered metal fuel includes, for example, powdered magnesium.
