GETTER DEVICES CONTAINING A COMBINATION OF GETTER MATERIALS

摘要

The invention relates to getter device containing a combination of getter materials comprising a mixture of cerium oxide and 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, compositions are preferably added to powders of other getter materials such as alkali metals hydroxides and desiccant materials effective for maintaining the vacuum in thermal insulation systems
