Gas generant compositions without highly toxic azides are provided which, upon combustion, are converted into gaseous products with only small amounts of solid combustion products thereby minimizing the gas filtration problem. Gas generants having ammonium nitrate safely phase stabilized by mixture with wet triaminoguanidine are provided. A process for safely preparing the gas generants is also provided. These compositions are especially suitable for inflating automotive and aircraft occupant restraint bags.


[ I claim:] [1.] An azide-free and binder-free gas generant composition that produces exhaust gases on combustion for inflating vehicle or aircraft occupant restraint devices in order to provide a clean inflating gas for the benefit of each vehicle or aircraft occupant, said composition consisting of:a. an oxidizer of the group consisting of a mixture of ammonium nitrate (AN) and potassium salt, and phase stabilized ammonium nitrate (PSAN), andb. a TAGN fuel of the group consisting of:i.) TAGN;ii.) a mixture of TAGN and GN; andiii.) a mixture of TAGN and...
