An improved nitrogen gas generating pyrotechnic composition is provided which consist of a stoichiometric mixture of an alkali metal azide or alkaline earth metal axide fuel and an oxidant consisting of a mixture of at least two metal oxides selected from the oxides of iron, silicon, manganese, tantalum, niobium and tin. The mixed metal oxides provide a synergistic effect and result in a composition having improved ignition delay time, burn rate and gas pressure as well as a reduction in toxic by-products and dust.
A solid nitrogen gas generating composition comprising a substantially stoichiometric admixture of (a) a fuel selected from the group consisting of alkali metal azides and alkaline earth metal azides, (b) a synergistically acting primary oxident component consisting of a mixture of at least two metal oxides selected from the group consisting of the oxides of iron, silicon, manganese, tantalum, niobium and tin, and (c) a residue control agent comprising a secondary metal oxide selected from the group consisting of the oxides of titanium, aluminium and zin...
