    摘要: 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.

    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.

    摘要: Nonevaporable getter alloys containing Zr, Co, and a third component A selected from the rare each metals and mixtures thereof, e.g., mischmetal. A most preferred alloy contains about 80.8 wt % Zr, about 14.2 wt % Co, and about 5 wt % A. These alloys are advantageous because they are suitable for general use, i.e., they have a relatively low activation temperature, are capable of sorbing a wide variety of gases, and minimize the environmental and safety risks associated with known nonevaporable getter alloys.
