Abstract
A process for manufacturing intermetallic compounds of the RB.sub.5 type where R is a mixture of two or more rare earth metals and B is nickel wherein the composition is determined, with respect to the desired desorption plateau pressure at 25.degree. C. in atmospheres absolute by means of the relationship EQU P.sub.25 =exp(10.60-5.70 X.sub.Ce -10.03 X.sub.La -8.46 X.sub.Pr -7.84 X.sub.Nd) wherein X is the weight fraction of the indicated element and X.sub.La +X.sub.Ce +X.sub.Pr +X.sub.Nd =1.
