Abstract
A combination of getter materials particularly suitable to maintain vacuum in devices which cannot be heated at temperatures higher than about 200.degree. C. The getter comprises: a mixture MO/Pd between an oxide of a transition metal MO chosen among cobalt oxide, copper oxide or their combinations and metallic palladium, wherein the latter is present up to about 2% by weight; and a moisture sorbing material. In some applications it is possible to add to this combination a barium- and lithium-based alloy, preferably BaLi.sup.4. Getter devices for containing such a combination are also described.
