摘要:
A process for synthesizing metal borohydride especially sodium borohydride directly from borax by the use of proton H at room temperature and pressure. Said process comprising the steps of: Providing proton H by the use of metals or alloys that can form hydrides with hydrogen. In this case, the metals or alloys are the carriers of proton H Proton H also can be provided from hydrogen gas by the use of catalysts located on the surface of carriers. Making the proton H enters the lattice of boron oxides Removing the oxygen from the lattice of boron oxides by the use of the carriers.

Disclosed herein is a method for preparing magnesium borohydride. The method includes the step of reacting a metal borohydride with a metal salt composition in a solvent, to form a reaction mixture. The metal salt composition comprises at least one magnesium salt. The metal borohydride and the metal salt composition are insoluble in the solvent. The method further includes the step of grinding the reaction mixture to produce a composition that includes magnesium borohydride; and removing the solvent from the composition. Another embodiment of this invention relates to a new material. The material is an orthorhombic crystal phase of magnesium borohydride.
