Abstract
Gas generation behavior of gas generating agents have been examined for mixtures using of 5-amino-1H-tetrazole (5-ATZ) as a fuel component together with various types of oxidizers (lithium perchlorate LiClO4 (LP), potassium perchlorate KClO4 (KP), sodium nitrate NaNO3 (SN), potassium nitrate KNO3 (KN), strontium nitrate Sr (NO3)2 (SrN), and copper(II) oxide (CuO) ), through deflagration test inside a closed 4 liter vessel. As a result, the degree of pressure gradients were in the order of LP > KP > SN > KN > SrN > CuO. Meanwhile, temperature gradients inside the vessel were in the same order. It was found that 5-ATZ/SN and 5-ATZ/KN mixtures' pressure gradients were larger and their generated gas temperature were lower than those of 5-ATZ/SrN mixture.
5-アミノ-1H-テトラゾールを燃料として，各種酸化剤（過塩素酸リチウム，過塩素酸カリウム，硝酸ナトリウム，硝酸カリウム，硝酸ストロンチウム，酸化銅（II））の混合物のガス発生挙動を4ℓの密閉容器を用いて調べた。ガス発生速度及び温度上昇速度は上述の酸化剤の順に小さくなった。また，硝酸ナトリウムと硝酸カリウムは硝酸ストロンチウムと比較して，ガス発生速度は速く，発生ガスの温度は低いことがわかった。
