Azide and doped iron oxide gas generating composition
First Claim
1. A solid nitrogen gas generating composition comprising a substantially stoichiometric admixture of an alkali metal azide or an alkali earth metal azide and a doped iron oxide, said doped iron oxide comprising an acicular iron oxide particle having an amount of up to 1.0% by weight of other metal oxide selected from nickel oxide and cobalt oxide impregnated into the iron oxide lattice, said doped iron oxide further having a particular size of less than 10 microns.

Abstract
A nitrogen gas generating composition is provided which consists of a stoichiometric mixture of an alkali metal azide or an alkali earth metal azide and a doped iron oxide of high chemical reactivity. The doped iron oxide contains up to 1.0% by weight of another metal oxide impregnated into its particle lattice. The resulting composition has improved properties of ignition delay time, total burn time, filter-ability and reduced toxic by-products.
