Solid-fuel rocket propellants comprising an oxidizer, an oxophilic metal-halophilic metal formulation, and a binder are described herein. Further described are processes for preparing such propellants and methods of reducing hydrogen chloride production via the combustion of such propellants. Non-limiting examples of such formulations include aluminum-lithium alloys.

Provided is a gas generating composition that maintains stable ignition performance for a long period. A gas generating composition includes: a gas generating agent including (a) fuel selected from a triazine compound and a guanidine compound, (b) an oxidizing agent including a Combination of (b-1) basic metal nitrate and (b-2) basic metal carbonate, and (c) a binder; and (d) an absorbent. The gas generating agent and the absorbent may not be integrally molded or may be integrally molded.
