Beschreibung
Zusammenfassung:	A combination of getter materials particularly suitable to maintain vacu um in devices which cannot be heated at temperatures higher than about 200.degree.C comprises: a) 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 b) a moisture sorbing material. In particular applications it is possible to add to this combination also a barium- and lithium-based alloy, preferably BaLi4. Getter devices for containing such a combination are also described.
