Abstract: An oxygen scavenging composition composed of a carrier and a metal coated, inert, porous particulate material having the metal substantially in a zero valence state. The composition is contained within the interior cavity of a container to scavenge oxygen therein. The composition may form at least a part of the interior surface of the container or be present therein in the form of a film, mat, sachet or ceramic.

Abstract: A combination of getter materials particularly suitable to maintain vacuum in devices which cannot be heated at temperatures higher than about 200° 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 BaLi4. Getter devices for containing such a combination are also described.

Abstract: A process is disclosed for making grids for flat-panel displays. The screen grids are coated with non-evaporable getter materials and the metal sheet forming the grid is coated with a coating that is as thick as the resulting grid and having at least the same surface area as the image formation zone of the flat-panel display. At least one side of the grid is coated with one or more non-evaporable getter materials and then parts of the sheet thereby coated are selectively removed. Some embodiments of grids produced with such a process are also disclosed.
