A gas-generating agent for inflating air bags comprises finely divided particles of a co-precipitation compound made by the following steps: (1) uniformly mixing in water to form an aqueous solution a composition comprising (a) one or a mixture of two or more alkali metal azides and/or alkaline earth metal azides and (b) an aqueous solution of a composition comprising one or a mixture of two or more nitrates or perchlorates of alkali metals or alkaline earth metals; or mixing (a) and (b) plus (c) finely divided particles of silicon dioxide; or mixing (a), (b) and (c) plus (d) fine glass powder; (2) mixing the resulting solution or suspension with a water-soluble organic solvent; and (3) separating and drying the co-precipitation compound thus obtained. The gas-generating agent will not produce toxic compounds such as sodium metal and sodium peroxide which might injure the car driver and passengers. Further, when low softening glass is added, the maximum temperature of combustion will be lowered.

A gas generating agent consisting essentially of finely divided particles of a co-precipitation product obtained by the steps of (1) preparing a uniform aqueous solution consisting essentially of (a) an azide component consisting of one or a mixture of two or more azides selected from the group consisting of alkali metal azides and alkaline earth metal azides, and (b) an oxidant component consisting of one or a mixture of two or more oxidants selected from the group consisting of alkali metal nitrates, alkali metal perchlorates, alkaline earth metal nitrates and alkaline earth metal perchlorates; (2) adding said aqueous solution to water-soluble organic solvent and thereby precipitating a co-precipitation product of (a) and (b) wherein the weight ratio of a/b is in the range of from 95/5 to 50/50; (3) separating and drying the co-precipitation product.
