Magnetic Properties of Alloys

Fine particles of LaNi5 were coated with a thin porous copper layer about 1 μm thick by a chemical plating method. The encapsulated alloy powder had a hydrogen storage capacity almost equal to that of the original alloy powder and its compacted pellet had a high thermal conductivity, leading to fast reaction kinetics. The pellet was able to withstand more than 5000 repeated hydriding-dehydriding cycles without disintegration.
