  • Patent number: 7090787
    Abstract: A zeolite and an organic binder are mixed with a solvent to form a paste (302). The paste is then cast or molded (304) into the desired shape. A portion of the solvent is allowed to evaporate from the paste, hardening the getter (306). Getters are often formed in sheets and cut (308) into individual pieces, called dibs, after the sheets have hardened. Even after the getter is hardened, significant amounts of solvent are retained by the getter. The getter is exposed to water vapor which displaces (310) the solvent from the getter. After the solvent is removed, the getter is dried (312) to remove additional water vapor. Because the water vapor does not bind as tightly to the zeolite getter, the water vapor is removed much easier than the solvent. The water may be removed by allowing the getter to dry naturally, or by a vacuum bake process.

  • Patent number: 7083825
    Abstract: An improved getter device and method for forming a calcium-rich getter thin film in an electronic vacuum device is disclosed. The getter device includes a powder of a Ca—Ba—Al ternary alloy composed of between 53% and 56.8% by weight of aluminum, from 36% to 41.7% by weight of calcium and from 1.5% to 11% by weight of barium. The method allows the formation of a calcium-rich getter thin film with a substantially reduced amount of released hydrogen in the vacuum device.

  • Patent number: 7001535
    Abstract: This invention describes a solution to the particular problem of liquid water formation in hydrogen getters exposed to quantities of oxygen. Water formation is usually desired because the recombination reaction removes hydrogen without affecting gettering capacity and the oxygen removal reduces the chances for a hydrogen explosion once free oxygen is essentially removed. The present invention describes a getter incorporating a polyacrylate compound that can absorb up to 500% of its own weight in liquid water without significantly affecting its hydrogen gettering/recombination properties, but that also is insensitive to water vapor.

  • Patent number: 6506319
    Abstract: Compositions containing getter material and getter devices for which gettering activity can be activated to applied temperatures that are lower than those temperatures required for activating the getter material alone are disclosed. In one aspect, a getter composition that includes a getter component and an activator component is provided. The getter component is selected from the group consisting of evaporable and non-evaporable getter materials. The activator component is effective to heat said getter material to a temperature greater than about 500° C. when said activator material is heated to a temperature of between about 280° C. and about 500° C. In some embodiments, the activator component is effective to bring the temperature of the getter material to greater than about 1,000° C. These materials can be used in devices and locations for which low applied activation temperatures are required.

    Abstract: There has been invented a codeposition process for fabricating hydrogen scavengers. First, a &pgr;-bonded allylic organometallic complex is prepared by reacting an allylic transition metal halide with an organic ligand complexed with an alkali metal; and then, in a second step, a vapor of the &pgr;-bonded allylic organometallic complex is combined with the vapor of an acetylenic compound, irradiated with UV light, and codeposited on a substrate.
