ABSTRACT:
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.
