Abstract
A solid composition for generating a nitrogen containing gas is provided. The composition includes an oxidizer and a 5-aminotetrazole fuel selected from anhydrous 5-aminotetrazole derivatives, salts, complexes, and mixtures 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.
