초록

A gas generating composition containing nickel oxide or iron oxide and an alkali metal or alkaline earth metal azide, preferably fabricated in the form of tablets or granules. Upon ignition the composition generates nitrogen gas. The gas generating reaction takes place at a relatively low temperature and the solid products of the reaction form a sinter that is readily retained by a filter. The composition is useful for inflating the bags of automobile passive restraint systems.

청구항

A process for the preparation of a gas generating composition adapted on burning to form nitrogen gas and a solid residue in the form of a sintered mass, comprising the steps of - a) preparing a mixture consisting essentially of dry particles of nickel oxide or iron oxide and dry particles of alkali metal azide or alkaline earth metal azide in molar proportions aDequate on burning to oxidize all the azide to nitrogen and form alkali metal oxide or alkaline earth metal oxide, b) adding sufficient fluid to the dry mixture to dissolve at least some of the a...
