Methods for forming alane are described. The method drives the alane producing chemical reaction by a mechanical energy source such as a ball mill and includes stabilization of the product with solvent. At least one of the reactants is insoluble in the solvent. Thus, the product is both stabilized and phase-separated from the reactant(s) immediately upon formation.
