New gas-generating agents for air bags have been investigated. Ammonium nitrate does not give off harmful gases nor leave solid residues but goes through contraction and expansion during a series of phase transitions that cause structural damage within the material. In this study, potassium-nitratephase-stabilized ammonium nitrate (PSAN) was prepared by a nonhazardous aqueous method. Ammonium nitrate-based propellants have low burning rates. Tetrazoles were selected as they have a large heat of formation and can be used as fuel components for ammonium nitrate-based gas-generating agents. A number of different experiments were conducted on the novel tetrazole/PSAN mixtures in order to evaluate their application as gas-generating agents.
