    摘要： A getter comprising a calcium-aluminum compound including about 39% to about 43% calcium by weight produces a calcium vapor when sufficiently heated. The calcium vapor can condense to form a calcium film on an inside surface of a sealed evacuated enclosure such as a CRT to getter reactive species from the enclosed volume. The calcium-aluminum compound, preferably CaAl2 powder, can be mixed with either nickel powder, titanium powder, or both.

    摘要： The present invention discloses metallic fiber boards having catalytic functionality and processes for producing the same. The boards are formed from a mesh of metallic fibers, each fiber having a first layer of an oxide and a second layer of a porous oxide. A catalyst, either disposed on the surface of the second layer, or dispersed within the second layer, provides catalytic functionality to the fiber board. The first layer is produced by thermal oxidation of the metallic fibers, while the second layer and catalyst are produced by thermal decomposition of precursor materials applied to the fiber board while in solution, typically as a spray of atomized droplets. The resulting boards are used to catalyze the combustion of hydrocarbons, especially methane, and particularly in household boilers.

    摘要： A powder of a composite material comprising a non-evaporable getter material with a palladium coating continuously sorbs hydrogen. Embodiments in which the coverage of the palladium coating over the particles of the NEG material is complete can sorb hydrogen without the need for an activation treatment. Other embodiments in which the palladium coverage is less than total but greater than about 10% can also sorb gaseous species other than hydrogen. Loose powders, pressed powders, and sintered powders of the composite material are incorporated into getter devices and into the evacuated spaces of double-walled pipes, dewars, and thermal bottles. Methods for preparing powders of these composite materials utilize evaporative, sputter, and CVD deposition techniques. Another method prepares powders of the composite material by a liquid phase impregnation process.

    摘要： A process for the conversion of boric acid to dry boron oxide by thermal decomposition is described. Boron oxide may be produced as a powder or in the form of pellets, and in either form may additionally be enclosed in a gas permeable container to control particulate contamination. Applications are further disclosed for the use of boron oxide formed by this process to remove water from evacuated chambers and from gases. Specific applications include removing water from both inert gases and reactive gases, especially halogen and halogenated gases. Further applications directed to optical amplifiers and gas purifiers are also discussed.
