Abstract
A pyrotechnic grain or body of a gas generant having a consolidated or pressed-on, particulate inert burn inhibitor layer thereon. The inhibitor may be a metal oxide, metal sulfide, silica, silicate compound or mixtures thereof. The metal oxide is preferably iron oxide. The metal sulfide is preferably molybdenum disulfide. The preferred inhibitor is a silicate compound, most preferably bentonite. The inhibitor layer most preferably covers only one face or side of the generant body, though it may cover both faces or less than the entire area of one or both faces. The generant may be any conventional formulation which generates nitrogen-containing gas, preferably an azide, and most preferably sodium azide. The generant body may be any shape, preferably a washer-shaped disc. An automotive gas bag inflator may contain a plurality of the composite, inhibited generant bodies, preferably a stack or side by side assembly of such composite, inhibited wafers.
