Abstract (en)
[origin: WO03072838A1] Disclosed are new Ca, Mg and Ni-containing alloys of the general formula: Cac Mgd Me b Ni1-z Tz 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 AI, 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 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.
