<p>A getter for use in a sealed enclosure in the form of a porous body formed from particles of a FAU zeolite having a silica to alumina molar ratio below 10 and particles of a high silica to alumina molar ratio zeolite, having a silica to alumina molar ratio of at least 20, bound together with an inorganic binder. The high silica to alumina zeolite is preferably de-aluminated zeolite FAU or *BEA.</p> |
