Gas generating compositions containing nitrotriazalone
First Claim
1. A composition consisting essentially of from about 25% to about 75% by weight nitrotriazalone and from about 25% to about 75% by weight of an anhydrous oxidizing salt having a cation selected from metals of group I-A of the Periodic Table (except sodium), calcium, strontium, or barium, said salt having an anion which is essentially free of carbon, hydrogen, and halogens.

Abstract
Automotive airbag gas generant formulation providing an alternative to commercially used formulations containing sodium azide. The composition contains from about 25% to about 75% by weight of 5-nitro-1,2,4-trizal-3-one (usually known as nitrotriazolone). The other principal ingredient of the composition is from about 25% to about 75% by weight of an anhydrous oxidizing salt having a cation selected from metals of Group I-A of the Periodic Table (except sodium), calcium, strontium, or barium, and an anion which is essentially free of carbon, hydrogen, or halogens. From about 0.1% to about 5% of a binder can be added, if necessary. An automotive airbag inflator containing the composition and a method for generating gas comprising the step of igniting the composition stated above are also disclosed.
