Technical Examples

A getter and method for making is provided for removing unwanted impurities from the main body of a sealed hermetic enclosure or package containing one or more devices or objects that have sensitivity to contact with the impurity. The getter may be formulated from granular or powdered materials that react with gas-phase impurities through a combination of chemisorption and absorption mechanisms to form one or more stable species. A porous receptacle is included that contains the getter material such that it cannot penetrate into the main body of the sealed package while allowing the gases in the main body of the package, including the target impurities, to pass freely into the receptacle where they are subsequently rendered immobile by the action of the getter material.
