ABSTRACT:
A gas generating composition comprises an organic fuel and an oxidizer wherein a component of the composition comprises an alkaline earth metal or alkali metal ion. The composition also comprises an ammonium salt coolant selected from the group consisting of ammonium halide, ammonium sulfate, and ammonium sulfamate. A preferred coolant is ammonium chloride. The anion of the ammonium salt on combustion of the gas generating composition reacts with the alkaline earth metal or alkali metal ion to produce a high melting point salt. The amount of coolant is an effective amount to obtain a reaction product which is substantially free of alkaline earth metal or alkali metal oxide. In the combustion reaction, the ammonium salt coolant reacts endothermically with other components of the reaction mixture reducing the combustion temperature of the reaction mixture.
