CA 2167388

A solid composition for generating a nitrogen containing gas is provided. The composition includes an oxidizer and a non-azide fuel selected from a bitetrazoleamine or a derivative or a salt or complex there? and mixtures thereof. The preferred bitetrazoleamine is 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.

Composé solide servant à produire un gaz riche en azote et comportant un oxydant, et un combustible non azidique choisi parmi un bitétrazoleamine ou l'un de ses dérivés ou sels ou complexes, ou leur mélange. Le bitétrazoleamine préféré est un bis-(1(2)H-tétrazol-5-yl)-amine ou l'un de ses sels métalliques ou un sel à cation non métallique d'une base à haute teneur en azote ou un de leurs complexes. Les sels et complexes en question sont généralement métalliques et le métal peut être de transition. Les métaux qui se sont avérés les plus utiles comprennent le cuivre, le bore, le cobalt, le zinc, le potassium, le sodium et le strontium. L'oxydant est généralement un oxyde ou un hydroxyde métallique. Le composé peut comprendre d'autres constituants tels que des oxydants secondaires, des modificateurs de la vitesse de combustion, des formateurs de cendres ou des liants.
