Abstract
An essentially particulate-free, non-toxic, odorless and colorless gas is generated in a pyrotechnic inflator device by using a eutectic solution of ammonium nitrate, guanidine nitrate and/or aminoguanidine nitrate, and minor amounts of polyvinyl alcohol and either potassium nitrate or potassium perchlorate. Ballistic modifiers such as triaminoguanidine nitrate (TAGN) or nitroguanidine (NQ) may be used as needed.
