Gas generant compositions

摘要

A gas generant composition contains as a fuel a mixture of a major portion of a triazole or tetrazole and a minor portion of a water soluble fuel; and an oxidizer component, at least 20 wt% of said oxidizer component being a transition metal oxide, such as CuO. Generant compositions in accordance with the invention autoignite in a range around 170 DEG C, providing autoignition of the generant without the need for separate autoignition devices. Also, the generant compositions are useful as autoignition pyrotechnic in autoignition devices.
