Metal oxide/azide gas generating compositions

摘要

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.
