ABSTRACT:
A process for production of a borohydride compound. The process comprises the steps of: (a) combining a boron-containing salt, at least one of a metal and its hydride; wherein the metal is Be, Mg, Ca, Sr, Ba, Al, Ga, Si or a transition metal; and a solvent in which the borohydride compound is soluble; (b) grinding a mixture formed in step (a) to form the borohydride compound; and (c) separating a solution comprising the borohydride compound.
