ABSTRACT:
A heatable sorption getter body for reactive residual gas clean-up in sealed vessels is provided. The getter body includes an insulating member, two electrical contacts, and a getter composition applied over surface portions of the insulating member. The insulating member serves as a carrier for the getter composition. The getter precursor composition is applied preliminarily after which the resulting dried assembly is subjected to sintering to complete preparation of the getter composition before the getter body is positioned in a sealed vessel.
