Experimental work has been carried out in search for the potential of 5,5'-azobis-tetrazole aminoguanidine (ABAG) / strontium nitrate Sr(NO3)2 mixture as a gas generating agent for airbag inflators. Altering the reducer/oxidizer ratio, linear burning rate, closed vessel test, 60-liter tank test, thermal analysis and qualitative and quantitative analyses of the combustion gases of the mixtures have been carried out, and the results have been compared with those of 5-amino-1H-tetrazole (5-ATZ) / Sr(NO3)2 mixture. The linear burning rate of ABAG / Sr(NO3)2 mixture reached its maximum when the mixture was ABAG rich. Internal pressure of the closed vessel reached its maximum when the mixture was ABAG rich, but the combustion temperature reached its maximum at a stoichiometric ratio. According to 60-liter tank test, the internal tank pressure of ABAG / Sr(NO3)2 was greater than that of 5-ATZ / Sr(NO3)2 and the hazardous gases such as HCN, CO, and NO2 were found in the combustion gases of ABAG / Sr(NO3)2 but the concentration of CO and NO2 gases were less than those of 5-ATZ / Sr(NO3)2. A new decomposition reaction of Sr(NO3)2 was suggested.
5,5’-アゾビステトラゾール・アミノグアニジン（ABAG）と硝酸ストロンチウムSr(NO3)2 混合物のエアバッグ用ガス発生剤としての可能性を探求するため，組成比を変化させ，線燃焼速度測定，密閉容器試験等を行い燃焼特性を調べた。また，量論比混合試料について，60リットルタンク試験を行い5-アミノ-1H-テトラゾール（5-ATZ）とSr(NO3)2 混合物と比較した。線燃焼速度はVielleの式に従い，ABAG混合物はABAG過剰で最大燃速になった。密閉容器試験ではABAG過剰で最大圧力となり，燃焼温度は量論混合物で最大となった。60リットルタンク試験では5-ATZ混合物よりABAG混合物のほうが燃焼圧力が高くなった。また，ABAG混合物の燃焼生成気体には有害なHCN，CO，NO2が同定されたが，HCN以外は5-ATZ混合物より少なかった。また，Sr(NO3)2の新しい分解反応式を提案した。
