    Abstract: A combination of materials is disclosed, comprising a getter alloy and one or more oxides chosen among Ag2O, CuO, MnO2 and Co3O4. To these combinations, a third component, consisting in an alloy rare earths, yttrium, lanthanum or their mixtures with copper, tin or their mixtures, is added. The combinations of the invention are useful for the preparation of getter devices which can be activated at relatively low temperatures, from about 280 to 500 DEG C, while the activation of the getter materials generally requires temperatures of from 350 to 900 DEG C. A few getter devices are also disclosed, which contain the combinations of materials of the invention.
