Hydrogen-less, non-azide gas generants
First Claim
1. A hydrogen-less gas generant composition consisting essentially ofA) between about 20 and about 40 wt % of a fuel and B) between about 60 and about 80 wt % of B) an oxidizer, said weight percentages of A) and B) being calculated on the total weight of A) plus B),between about 60 and 95 wt % of said fuel A) comprising a fuel component i) selected from the group consisting of cupric bitetrazole, zinc bitetrazole and mixtures thereof, andbetween about 5 wt % and about 40 wt % of said fuel A) comprising a fuel component ii) selected from the group consisting of cupric dicyanamide, zinc dicyanamide and mixtures thereof,between about 70 and 100 wt % of said oxidizer B) comprising an oxidizer component iii) selected from the group consisting of CuO, Fe2 O3, and mixtures thereof, andup to about 30 wt % of said oxidizer B) comprising an oxidizer component iv) selected from the group consisting of alkali and alkaline metal salts of nitrate, chlorate, perchlorate, and mixtures thereof.

Abstract
A gas generant composition contains no hydrogen, using as the major fuel component cupric and/or zinc bitetrazole and as a major oxidizer component CuO and/or Fe2 O3. A minor fuel component may be a salt of dicyanamide which reduces processing sensitivity of the composition. A minor oxidizer component may be a nitrate, chlorate, or perchlorate salt.
