    摘要： A liquid metal cooled directional solidification process provides improved solidification characteristics at the solidification front. In the process, a mold is filled with molten metal; and a solidification interface is caused to pass through the molten metal by progressively immersing the mold into a cooling liquid. The cooling liquid is a eutectic or near eutectic metal composition. A directional solidification furnace includes a heating furnace, a liquid cooling bath and a mold positioner. The heating furnace has an open bottom end through which a heated mold containing molten metal is lowered from the furnace. The liquid cooling bath comprises a molten eutectic or near eutectic metal composition positioned beneath the open end of the furnace. The mold positioner gradually lowers the heated mold from the furnace, through the open end and immerses the mold into the liquid cooling bath.

    摘要： 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.
