Patent ID: 7578895

Claim:
A perchlorate-free solid pyrotechnic flash bang composition consisting essentially of: an oxidizer component consisting essentially of: an oxidizer component consisting essentially of from about forty-five weight percent (45.0%) to about sixty weight percent (60.0%) potassium nitrate, and wherein the mean particle size of the oxidizer particles is from about twenty microns (20.0 μm) to about thirty-five microns (35 μm); a pH stabilizer component consisting essentially of from about five-tenths of one weight percent (0.5%) to about one an one-half weight percent (1.5%) boric acid; and a free flow/anti-caking component consisting essentially of from about two-tenths of one weight percent (0.2%) to about eight-tenths of one weight percent (0.8%), and has a mean particle length of from about one-tenths micron (0.1 μm) to about four-tenths micron (0.4 μm) and consists essentially of silicon dioxide; a fuel component consisting essentially of: a metallic fuel component consisting essentially of from about thirty-five weight percent (35%) to about forty-five weight percent (45.0%) flaked aluminum particles coated with carbon or graphite comprising up to about one-half of one weight percent (0.5%) of the composition, and wherein said flaked aluminum particles have a mean particle size from about three-tenths micron (0.3 μm) to about twenty-five microns (25.0 μm), and a surface area of from about seven square meters per gram (7 m 2 /g) to about twelve square meters per gram (12 m 2 /g); and a non-metallic fuel component consisting essentially of about five weight percent (5.0%) to about ten weight percent (10.0%) of a non-metallic fuel consisting essentially of sulfur, wherein said sulfur has a mean particle size no greater than about fifty microns (50.0 μm); and a ballistic accelerant component consisting essentially of from about zero weight percent (0.0%) to about ten weight percent (10.0%), said ballistic accelerant component selected from the group consisting of nitrocellulose, black powder, and commercially available single or double base propellants.
