| 摘要 |
The present invention discloses a combination of gas adsorbing materials, particularly suitable for maintaining a vacuum in devices which cannot be heated at temperatures higher than about 200 degree C, said adsorbing materials comprising: a) a MO/Pd mixture of a transition metal oxide, MO, selected from cobalt oxide, copper oxide or the combinations thereof, and metallic palladium, said mettalic palladium being present in up to about 2 percent by weight; and b) a humidity adsorbing material. In particular embodiments, addition of a barium-based and a lithium-based alloy to said materials combination is possible, preferably BaLi4. The present invention further discloses gas adsorbing devices for the containment of said combination of gas adsorbing materials.
