ABSTRACT:
Gas generating compositions contain a non-azide fuel, phase stabilized ammonium nitrate (PSAN) and silicon. These gas generant compositions yield inflation gases having a reduced content of undesirable gases such as NO.sub.x and CO. The gas generanting compositions preferably contain 5-aminotetrazole at a concentration of 15-30 wt. % as the fuel, an oxidizer system at a concentration of 35-80 wt. % which comprises phase stabilized ammonium nitrate, at least 0.5 wt. % silicon, about 1 wt. % iron oxide and at least one material selected from binders and processing aids. The gas generating compositions are useful for inflating vehicle occupant restraint devices and for pyrotechnically operated fire suppression devices. The high level of gases produced by the compositions of the invention allow for smaller inflators which reduce the costs of production and the saving of weight.
