Abstract
A eutectic solution of ammonium nitrate and either aminoguanidine nitrate (AGN) or guanidine nitrate (AN) in the form of a present pellet is used to generate a particulate-free, non-toxic, odorless and colorless gas that is useful wherever an immediate source of such gas is required, such as the inflation of an occupant restraint air bag. The use of the material in the form of a eutectic totally eliminates pellet cracking. Moreover, the addition of a minor amount of potassium nitrate to the eutectic solution eliminates the ammonium nitrate phase change due to temperature cycling without adversely affecting the pressed pellets' freedom from cracking due to said temperature cycling.
