Title: Solid propellants for generating hydrogen

Abstract: Disclosed are storable solid propellant compositions based on complex metal oron compounds of the general formula M(BH.sub.4).sub.x or M(BD.sub.4).sub.x, (where M equals a metal and x equals the valence of the metal M; M is an alkali metal or an alkaline earth metal; H is hydrogen, and D is deuterium) and ammonium salts of the general formula (NH.sub.4).sub.n Y or deuteroammonium salts of the general formula (ND.sub.4).sub.n Y (where Y represents an anion with a total charge of n; N is nitrogen, H is hydrogen, and D is deuterium) combined stoichiometrically or in varying molar ratios. The stoichiometric blend is employed in a method for producing hydrogen or deuterium that contains nitrogen as an inert diluent and is acceptable for use in HF/DF chemical lasers, the gas dynamic laser (GDL), or as a source to generate hydrogen containing an inert diluent.
