Abstract
Nonazide gas generating compositions are formed from a nonazide fuel, an oxidizer, a slag former, and a built-in catalyst comprising an alkali metal, alkaline earth metal, or transition metal salt of tetrazoles, bitetrazoles, and triazoles, or a transition metal oxide. The built-in catalyst promotes the conversion of nitrogen oxides (NOx) and carbon monoxide to nitrogen gas (N2) and carbon dioxide, respectively. The gas generants are therefore nontoxic and useful for inflating a vehicle occupant restraint system.
