This invention aims to provide a gas generating composition of a gas generator for an air bag, which composition produces less combustion residues and is easily adsorbed. This composition comprises azide of alkali metal or alkaline earth metal, metallic silicide, and perchlorate or nitrate of alkali metal or alkaline earth metal. The combustion residues of the azide are changed to be glass silicate by the metallic silicide and caught by a filter of the gas generator, so that they do not pass through the filter of the gas generator nor make holes in the air bag unlike a conventional gas generator. And, the addition of silicon dioxide further improves the catching of the combustion residues of the azide. |
