Abstract
Gas generating compositions or propellants are provided which comprise a non-azide fuel which is a transition metal complex of an aminoarazole. Preferred transition metal complexes are zinc and copper complexes of 5-aminotetrazole and 3-amino-1,2,4-triazole, with the zinc complexes most preferred. The propellant compositions also include a conventional oxidizer, such as potassium nitrate or strontium nitrate. These compositions are useful for generating a nitrogen-containing gas for a variety of applications, especially for inflating air bags in automotive restraint systems, as well as other inflatable devices.
