Abstract
Infrared illuminant compositions are disclosed which produce significant quantities of infrared radiation when burned but which produce very little visible light. The infrared illuminant compositions provide specific illumination in the spectral range visible with night vision devices. The disclosed infrared illuminant compositions include ammonium nitrate as the main oxidizer, an infrared generator such as cesium nitrate, rubidium nitrate, or mixtures thereof, and a fuel. By eliminating potassium and its direct and indirect visible light contributions, from the illuminant compositions, improved concealment indexes are obtained. Other additives, including conventional binders and burn rate modifiers may be used as to tailor the performance and physical characteristics of the infrared illuminant composition.
