    Abstract: Compositions containing getter material and getter devices for which gettering activity can be activated at 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.degree. C. when said activator material is heated to a temperature of between about 280.degree. C. and about 500.degree. C. In some embodiments, the activator component is effective to bring the temperature of the getter material to greater than about 1,000.degree. C. These materials can be used in devices and locations for which low applied activation temperatures are required.

    Abstract: A process is disclosed for producing non-evaporable getter materials having high porosity and improved gas sorption rates. The process includes mixing together a metallic getter element, a getter alloy and a solid organic compound, all three components being in the form of powders having specific particle sizes. The mixture is subjected to a compression of less than about 1000 kg/cm.sup.2 and is sintered at a temperature between about 900.degree. C. and about 1200.degree. C. for a period between about 5 minutes and about 60 minutes. The getter material thus obtained is used to produce getter bodies shaped as pellets, sheets or discs having better mechanical strength than similar bodies of other getter material having comparable porosity.

    Abstract: A superconductor which is superconducting of a predetermined high field and low temperature is formed by combining a plurality of metal bodies to form a composite structure. The metal bodies are selected from transition metals such as niobium, tantalum, zirconium, hafnium and vanadium, and alloys of such metals, alternate bodies being formed of ductile alloys of the metals which are not superconducting at the predetermined high field. The alternate bodies of transition metals are reacted to form a ductile superconducting ternary alloy zone at the interfaces of these bodies. The extent of the reaction is limited so as to maintain areas of transition metal and transition metal alloys which are not superconducting at the high field. The composite structure is reduced sufficiently that each non superconducting zone is less than 1000A.degree. thick and serves as an artificial pinning site for each adjacent superconducting zone.

    Abstract: The chemical resistance of a gettering device comprising a mixture of barium-aluminium powder and nickel powder compressed in a metal holder is considerably increased by using nickel powder having a specific surface smaller than 0.15 m.sup.2 per gram and an average grain size smaller than 80 microns, while the barium aluminium powder has an average grain size smaller than 125 microns. The said gettering device is extremely suitable for use in the manufacture of a color display tube in which the gettering device is to be placed inside the envelope of the tube before certain parts of said envelope are sealed together at a high temperature.
