Solid smokeless propellants and pyrotechnic compositions for rocket and gas generation systems

Solid gas generant compositions produce low particulates of the slightly-soluble or insoluble type when combusted. More specifically the solid gas generants and/or ignition compositions are provided which include an effective combination of phase stabilized ammonium nitrate (PSAN) as a oxidizer component and azodiformamidine dinitrate (AZODN) as the fuel component. Most preferably, the AN is phase stabilized with a phase stabilizing effective amount of a phase stabilizer selected from potassium perchlorate (KP) and/or potassium nitrate (KN).
