Abstract
To a gas generant composition comprising a fuel component which includes a triazole compound and/or tetrazole compound with an acidic hydrogen and an oxidizer component which includes a transition metal oxide, is added a chelating agent, such as ethylenediaminetetraacetic acid (EDTA) to provide long-term stability to the gas generant composition.
Claims5
Gas generant compositions comprising a fuel component and an oxidizer component, said fuel component comprising a tetrazole compound having an acidic hydrogen and/or a triazole compound having an acidic hydrogen and said fuel component comprising a transition metal oxide, wherein the improvement comprises said gas generant composition containing a chelating agent at between about 0.05 and about 5 wt % relative to the total weight of said fuel component and said oxidizer component.
