Abstract
Systems and methods for producing microcrystalline alpha alane are provided herein. An exemplary process comprises the elimination of the crystallization aid lithium borohydride through the use of excess lithium aluminum hydride or sodium borohydride. Further exemplary processes comprise methods for passivating microcrystalline alpha alane using a weak acid in a nonaqueous solvent solution.
