Abstract
A composition is provided which has at least one salt of 5-nitraminotetrazole and an at least one oxidizer selected from among inorganic nitrates, inorganic nitrites, metal oxides, metal peroxides, organic peroxides, inorganic perchlorates, inorganic chlorates, metal hydroxides, and mixtures thereof. The compositions are useful in the gas generant field.
Claims18
A gas generant composition comprising a fuel effective amount of at least one metal salt of 5-nitraminotetrazole and an oxidizing effective amount of at least one oxidizer selected from the group consisting of metal oxides, metal peroxides, metal hydroxides, and mixture thereof, wherein combustion of said composition produces a gas useful for inflating automobile air bags and a solid slag.
A gas generant composition consisting essentially of:
- a fuel effective amount of at least one metal salt of 5-nitraminotetrazole, wherein the metal is selected from the group consisting of metals of Group Ia, Ib, IIa, IIb, IIIa, IVb, VIb, VIIb or VIII of the Period Table (Merck Index (9th Edition 1976));
- an oxidizing effective amount of an oxidizer selected from the group consisting of metal oxides, metal peroxides, metal hydroxides, and mixtures thereof;
- a secondary oxidizer;
- a secondary fuel selected from the group consisting of a metal dicyanamide, a metal bitetrazole, tetrazoles, aminotetrazoles, triazoles, salts and complexes thereof, and mixtures thereof;
- and
- a binder, wherein combustion of said composition produces a gas useful for inflating automobile air bags and a solid slag.
