초록

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 emplo...
