초록

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 pr...
