Abstract

High nitrogen nonazide gas compositions, useful in inflating passenger restraint gas inflator bags, comprise a nonmetal salt of triazole or tetrazole fuel, phase stabilized ammonium nitrate (PSAN) as a primary oxidizer, a metallic second oxidizer, and an inert component such as clay or mica. The combination of these constituents results in gas generants that are relatively more stable and less explosive, have improved ignitability and satisfactory burn rates, have sustained combustion throughout the various combustion pressures at the inflator level, and generate more gas and less solids than known gas generant compositions.
