Abstract: Disclosed are new Ca, Mg and Ni-containing alloys of the general formula: (CacMgdMe)b(Ni1-zTz)a where: M is at least one metal selected from the group consisting of Y, Ce, La, Pr, Nd, Th, Nd, Ti, V, Zr, Ta, Hf, Sr, Ba and Misch metals; T is at least one element selected from the group consisting of Al, Zn, Cu, Fe, Co, Mn, Cr, Mo, W, Si, Ga, Ge, In, Sn, Ag, C and B; a is an integer equal to 2 or 5; z is a number ranging from 0 to 0.5; and when a is equal to 2, then 0.9?b?1.1; and when a is equal to 5, then either 1.75?b?2.25 or 0.75?b?1.31. These alloys which are of the AB2, A2B5 or AB5 types, may be single phase or multiphase and are useful for reversibly absorbing hydrogen from a gas phase. Also disclosed is a method for preparing the above alloys.
