Combination of getter materials and device for containing the same |
摘要 |
A combination of getter materials particularly suitable to maintain vacuum in devices which cannot be heated at temperatures higher than about 2000C 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. <IMAGE> |
