An anhydrous 5-aminotetrazole or "5-AT" based gas generating composition for use in passive restraint devices, such as air bags and a method of preparing the same that is devoid of metal oxides. The gas generating composition includes 5-AT with a blend of oxidizers such as potassium perchlorate and potassium nitrate. This gas generating composition is devoid of metal oxides, such as copper oxide or iron oxide, which form an insoluble slag when ignited. After ignition, the combustion products of the gas generating composition can be filtered with a filter...


[ What is claimed is:] [1.]1. A metal oxide free, gas generating composition comprising in combination, by weight, approximately 38% 5-aminotetrazole, approximately 12% potassium perchlorate, approximately 50% potassium nitrate, and absent metal oxides.
