1H-1,2,4-triazole (1Htri) - metal complexes were investigated as promising gas generators for airbag inflators. The SC-DSC measurements, sensitivity tests, and deflagration tests were conducted to investigate the influences of the metals on the decomposition characteristics of the complexes. The SC-DSC measurements revealed the 1Htri-metal interaction stabilize the complexes. Regarding the sensitivity tests, 1Htri -metal complexes were categorized in the same class 7 of friction sensitivity test and class 8 of drop hammer sensitivity test. Besides, electrostatic sensitivity test, only copper and silver complexes were different from its pure azole which both complexes were categorized as class 3 according to JIS. Furthermore, the deflagration test indicated the proportion of metals in the substance had a substantial impact on burning rate, which was as verified by the relation of metal percentage and maximum pressure rate.
