Preparation of anhydrous tetrazole gas generant compositions

Abstract

A solid composition for generating nitrogen containing gas is provided. The composition includes an oxidizer and a non-azide fuel selected from anhydrous tetrazoles, derivatives, salts, complexes, and mixtures thereof. Preferred tetrazoles include 5-aminotetrazole and bis-(1(2)H-tetrazol-5-yl)-amine, a metal salt, a salt with a nonmetallic cation of a high nitrogen content base or a complex thereof. The salts and complexes are generally metal salts and complexes. The metal can be a transition metal. Metals that have been found to be particularly useful include copper, boron, cobalt, zinc, potassium, sodium, and strontium. The oxidizer is generally a metal oxide or a metal hydroxide. The composition can include certain other components such as secondary oxidizers, burn rate modifiers, slag formers, and binders.
