Zusammenfassung:Methods of making and resultant compositions thereof, which include a gas generant having a coating including an inorganic combustion inhibitor. Such coated gas generants are useful in pyrotechnic compositions and ignition materials, and may be employed, for example, in inflatable restraint systems. The ratio of coated and uncoated gas generant bodies within an airbag inflator may be tailored to provide S-curve inflation performance. Spray application of aqueous mixture including the combustion inhibitor onto the gas generant body provides a rapid way to achieve a thin but robust coating.
