Abstract
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.
