  • Patent number: 6136114
    Abstract: Gas generant compositions are disclosed that generally include an a fuel source including a compound having a fuel portion and a fuel oxidizing portion, a fuel oxidizer, and a borohydride catalyst of the oxidation of said fuel portion by said fuel oxidizing portion and said fuel oxidizer to produce gaseous reaction products. In preferred compositions the fuel source is comprised of the elements nitrogen, carbon, hydrogen and water and combusted to produce N.sub.2, CO.sub.2 and H.sub.2 O as the primary reaction products. Preferably, the fuel oxidizer is a metal nitrate, and particularly potassium nitrate, because the potassium will generally be included in solid products and not in the form of a potentially harmful gas. It is also preferred that the combustion reaction be catalyzed using borohydrides. Potassium borohydrides, such as K.sub.2 B.sub.12 H.sub.12 and K.sub.2 B.sub.10 H.sub.10, are particularly preferred.
