Abstract

An infrared illuminant composition and flares produced therefrom having increased burn rate and increased infrared intensity while maintaining low visible light intensity. The composition comprises potassium nitrate, cesium nitrate, hexamine, boron, silicon, ferric oxide and a binder. A process to produce infrared illuminant flares prevents or substantially eliminates chunking out of burning pieces of the illuminant at pressing increments in the flares. A multi-stepped pressing foot (10) is used for pressing the composition in the case. <IMAGE>
