Abstract
Solid gas generant compositions produce low particulates (e.g., condensed ash) when ignited. The solid gas generant compositions most preferably include a nitramine, at least one oxidizer selected from nitrates of strontium or cerium, in admixture with or without potassium perchlorate, and a binder. Graphite may optionally be employed. The gas generant compositions are usefully employed in inflatable vehicle occupant passive restraint systems (e.g., air bag systems).
