  • Multi-ingredient gas generators
    Patent number: 4376002
    Abstract: An improved nitrogen gas generating pyrotechnic composition is provided which consist of a stoichiometric mixture of an alkali metal azide or alkaline earth metal axide fuel and an oxidant consisting of a mixture of at least two metal oxides selected from the oxides of iron, silicon, manganese, tantalum, niobium and tin. The mixed metal oxides provide a synergistic effect and result in a composition having improved ignition delay time, burn rate and gas pressure as well as a reduction in toxic by-products and dust.
    Type: Grant

  • Azide and doped iron oxide gas generating composition
    Patent number: 4243443
    Abstract: A nitrogen gas generating composition is provided which consists of a stoichiometric mixture of an alkali metal azide or an alkali earth metal azide and a doped iron oxide of high chemical reactivity. The doped iron oxide contains up to 1.0% by weight of another metal oxide impregnated into its particle lattice. The resulting composition has improved properties of ignition delay time, total burn time, filter-ability and reduced toxic by-products.
