Synergistic composite pyrotechnic material

摘要

The invention provides a pyrotechnic composite and process for preparing the same, wherein the pyrotechnic composite comprises a mixture of an alkaline earth metal sulfate, particulate boron and at least one additional particulate metal which is capable of exothermically reacting with boron. The exothermic reaction between the components of the pyrotechnic composite releases a thermal radiation of at least about 300 W/cm2-Steradian and a visible light energy of at least about 1.0x104 LUX.
