Abstract
High nitrogen nonazide gas compositions, useful in inflating passenger restraint gas inflator bags, contain a high energy substituted tetrazole or bitetrazole that forms a naturally occurring hydrate and phase stabilized ammonium nitrate (PSAN) as a primary oxidizer. The combination results in gas generants that are relatively more stable and less explosive, have improved ignitability and burn rates, and generate more gas and less solids at lower operating pressures than known gas generant compositions.
