Gas generant compositions exhibit low autoignition temperatures. In preferred forms, the gas generant compositions include azobisformamidine dinitrate (AZODN) and a eutectic mixture (comelt) of silver nitrate and potassium nitrate. The comelt of silver nitrate and potassium nitrate is most preferably present in the formulations of the invention in an amount to achieve a low autoignition temperature of between about 140° C. (284° F.) to about 160° C. (320° F.). The compositions of the invention may include a variety of auxiliary components typically employed in conventional gas generant compositions for their intended purpose. For example, especially preferred formulations of the present invention will include a powdered metal or metal oxide as a combustion catalyst to speed the decomposition reaction and also as a combustion aid to facilitate the ignition of the primary propellant or gas generant.
