Compositions and methods relating to gas generants used in inflatable restraint systems. The gas generant grains formed via spray drying techniques of the present disclosure provide superior performance, including high burn rates and high gas yields. Further, processing of the gas generant grain products can be streamlined. Such gas generants include by way of non-limiting example, guanidine nitrate, basic copper nitrate, and a secondary oxidizer, such as potassium perchlorate.
1. A method for making a gas generant comprising: forming an aqueous mixture by mixing together guanidine nitrate, basic copper nitrate, about 1% to about 30% by weight of a secondary oxidizer comprising a perchlorate salt, and an aqueous medium comprising water;spray drying the aqueous mixture to produce a powder, wherein the powder comprises the guanidine nitrate, the basic copper nitrate, and the secondary oxidizer comprising the perchlorate salt; andpressing the powder to produce a gas generant grain. 2. The method of claim 1, wherein the aqueous mix...
