ABSTRACT:
A process for manufacturing a gas generating material includes preparing a hot solution of a metal azide, preferably sodium azide, with metal oxide particles, preferably iron oxide particles, suspended in the solution. The metal azide is precipitated from the solution. The step of precipitating the metal azide from the solution includes cooling the hot solution to decrease the solubility of the metal azide in the solute. The metal azide precipitate and the iron oxide particles are then separated from the liquid.
