摘要： A first heat treatment is carried out in which a material powder comprising magnesium is kept in the atmosphere of hydrogen gas and the temperature and pressure in the atmosphere of hydrogen gas are maintained in the temperature-pressure region in which single Mg and H2 coexist in a thermodynamically stable state, whereby the coating on the surface of the material powder is removed. Next, a second heat treatment is carried out in which the temperature and pressure in the atmosphere of hydrogen gas are changed and maintained in the temperature-pressure region in which MgH2 exists in a thermodynamically stable state. Hence, Mg from which the coating is removed reacts promptly with H2, and MgH2 is produced at high yield. Magnesium-based hydrides containing high purity MgH2 can thus be obtained by supplying energy less than that required for the related art that requires an activation treatment.
