ABSTRACT:
A metal material, which is capable of reacting with hydrogen to form a metal hydride, is simultaneously granulated and conditioned with hydrogen to activate the metal material to a state in which it is capable of readily reacting with and absorbing hydrogen. The granulation and activation are achieved by heating the metal material to a temperature of at least about 200.degree. F. and treating the heated metal material with hydrogen, while concurrently subjecting the metal material to mechanical impact to reduce the average particle size thereof to less than about 1 centimeter.
