1. An extrudable gas generant composition comprising:

  • at least one non-azide, organic, nitrogen-containing fuel;

    at least one copper-containing compound selected from the group consisting of basic copper nitrate, cupric oxide, a copper diammine dinitrate-ammonium nitrate mixture wherein ammonium nitrate is present in the mixture in a range of about 3 to about 90 weight percent, copper diammine bitetrazole, a copper-nitrate complex resulting from reaction of 5-aminotetrazole with basic copper nitrate, and combinations thereof;

    a perchlorate additive comprising at least one perchlorate material selected from the group consisting of alkali metal perchlorates and ammonium perchlorate, the perchlorate additive present in a relative amount effective to result in a gaseous effluent, when the gas generant composition is combusted, having a reduced content of at least one species selected from the group consisting of carbon monoxide, ammonia, nitrogen dioxide and nitric oxide, as compared to a same gas generant composition free of the perchlorate additive; and

    a polymeric binder material effective to render the gas generant composition extrudable.
