Abstract
Hydrogen gettering alloys which contain nickel, mischmetal, and zirconium, and may optionally contain one or more of cobalt, copper, iron, aluminum, tin, titanium and silicon, overcome many of the deficiencies of the existing getter technology. These alloys may be readily activated for use and regenerated for reuse. They are conveniently prepared using available furnace technology.
