ABSTRACT:
A gas generating grain has a water-based particulate booster coating thereon. The coating comprises an alkali metal azide, a water-soluble inorganic oxidizer in approximately a stoichiometric proportion of oxidizer to azide, and a nucleating amount of a small particle size metal oxide, preferably selected from the group consisting of iron oxide, nickel oxide and aluminum oxide. The coating is applied to said grain from a water slurry and dried, and when dried has an average particle size of less than about 50 microns.
