The absorption of hydrogen by the magnesium-rich alloys LnMg12 (Ln La, Ce, mischmetal), La2M17 and Ce5Mg41 was investigated. The alloys decompose during hydriding to give magnesium hydride and the corresponding rare earth hydride. A comparative study of the hydriding and dehydriding processes was carried out at two different temperatures. In addition, alloys with compositions corresponding to the formula CeMg11M (M V, Cr, Mn, Fe, Co, Ni, Cu, Zn) were prepared and their absorption and desorption rates were compared with those of CeMg12 and La2Mg17. The hydriding rate is not changed significantly by the presence of a 3d element but the dehydriding rate is greatly enhanced by the presence of vanadium, chromium, manganese, iron or nickel. These results are discussed.read more
