Abstract
Official abstract text for this publication.
A getter device containing a combination of getter materials is described. The device has a mixture of cerium oxide, copper oxide and metallic palladium for the removal of hydrogen and carbon monoxide in vacuum applications, particularly suitable to be used in vacuum insulation applications. This combination of getter materials is preferably added to powders of other getter materials such as alkali metals hydroxides and desiccant materials that are effective for maintaining the vacuum in thermal insulation systems.
First claim
Opening claim text (preview).
The invention claimed is: 1. A getter device including a combination of getter materials comprising: a mixture of powders of transition metals oxides and metallic palladium, wherein an amount of said metallic palladium is in a range between 0.2 and 2% by weight with respect to a total weight of said transition metals oxides, said mixture of powders of transition metals oxides and metallic palladium have a surface area between 5 and 50 m 2 /g and comprise cerium oxide and copper…
