  • Patent number: 6126764
    Abstract: A pyrotechnic fuel material for a booster in a pyrotechnic system having an adjacent igniter. In one embodiment, a powdered BaAl.sub.4 compound is used as the booster pyrotechnic fuel. In another embodiment, a powdered zirconium/nickel alloy is used as the booster pyrotechnic fuel. Both the powdered BaAl.sub.4 compound and the powdered zirconium/nickel alloy exhibit ignition sensitivity thresholds on the order of millijoules, thereby allowing for increased safety in manufacturing and handling over elemental powdered metal pyrotechnic fuels normally used for the entire pyrotechnic system.
