摘要：

The performance of boron/potassium nitrate/5-amino-1H-tetrazole-based pyrotechnic igniter, used as an initiator in airbag gas generators, was investigated. It was found that 5-amino-1H-tetrazole could significantly improve the stability, burning characteristics and ignition capability of boron/potassium nitrate igniter. When mixed with mass ratio of 27/73/10, boron/potassium nitrate/5-amino-1H-tetrazole showed an activation energy of 396.90 kJ mol(-1). When used to ignite the guanidine nitrate and basic cupric nitrate gas-generating agent, it resulted in an increase by 19 % in the maximum pressure, as well as a decline in the burning time and ignition delay time by 12 and 24 %, respectively.
