Thermally stable gas generant compositions incorporate a combination of nitroguanidine, one or more nonazide high-nitrogen fuels, and phase-stabilized ammonium nitrate or a similar nonmetallic oxidizer that, upon combustion, result in a greater yield of gaseous products per mass unit of gas generant, a reduced yield of solid combustion products, and acceptable burn rates, thermal stability, and ballistic properties. These compositions are especially suitable for inflating air bags in passenger-restraint devices.
[ We claim:] [1.]1. A gas generant composition consisting of a hydrated or anhydrous mixture of:nitroguanidine and at least one nonazide high-nitrogen fuel selected from the group consisting of guanidines, tetrazoles, triazoles, salts of tetrazoles, and salts of triazoles; andphase stabilized ammonium nitrate as an oxidizer,wherein said composition has a melting point of at least 115.degree. C., the ammonium nitrate is phase stabilized by coprecipitating with potassium nitrate, said nitroguanidine comprises 1%-26% by weight of said mixture; said at least...
