Abstract: A method of producing magnesium-based hydrides is provided that can enhance production efficiency while securing safety. An Mg ingot including Mg is cut to make a number of Mg flakes. An accumulated matter made by accumulating a number of Mg flakes are compressed and shaped to form a compressed matter of Mg flakes. The compressed matter of Mg flakes is placed in hydrogen gas such that Mg reacts with hydrogen gas, to produce magnesium-based hydrides. Since the Mg flakes have a low risk of explosion, this allows safer production of magnesium-based hydrides. Moreover, compression of the Mg flakes causes distortion in the flakes, which makes it easy for Mg to react with hydrogen gas, allowing enhancement in yield of magnesium-based hydrides.

Abstract: A nonreversible metal hydride for use as a hydrogen fuel. The nonreversible metal hydride is formed from an intermetallic compound having the formula Ca1+aLi2+b. The Ca1+aLi2+b is formed by melting amounts of elemental lithium and calcium together by induction heating in an argon atmosphere. The Ca1+aLi2+b is cooled and crushed into a powder.
