Abstract

See full text

A getter wire is made by wrapping alternate layers of getter metal and refractory metal around an ingot of refractory metal. The composite ingot thus formed is reduced to wire, preferably by extrusion and drawing. The multi layers of refractory and getter metals can then be heated to form an alloy of the two metals from which the getter is evaporated during use. A preferred combination is tantalum as refractory and titanium as getter.
