  • Method for producing a nonevaporable getter
    Patent number: 6398980
    Abstract: A process is provided for the production of porous non-evaporable getter materials comprising at least one first element selected from Zr and Ti and at least one second element selected from V, Cr, Mn and Ni. The starting metal powders are produced by reduction of the corresponding oxides, with calcium hydride and the thus obtained powders are compacted and sintered at a value of pressure and temperature in a given range. The getter materials due to the production process, have a novel distribution of chemical composition through the getter body, resulting in an improved combination of mechanical and gas-sorption properties.
    Type: Grant
    Filed: June 8, 2001
    Date of Patent: June 4, 2002
    Assignee: Tovarischestvo S Ogranichennoi Otvetstvennest Ju “Tekhnovak+ ”
    Inventors: Nina Pavlovna Reutova, Serguej Jurievich Maneghin, Jury Mikhailovic Pustovoit, Vladimir Leonidovich Stoljarov, Vladimir Borisovich Akimenko
  • Nonevaporable getter
    Patent number: 6322720
    Abstract: It is described a process for the production of porous non-evaporable getter materials comprising at least one first element selected between Zr and Ti and at least one second element selected among V, Cr, Mn and Ni, wherein the starting metal powders are produced by reduction with calcium hydride of the corresponding oxides and the thus obtained powders are compacted and sintered at a value of pressure and temperature in a given range; also described are getter materials that, due to the production process, have a novel distribution of chemical composition through the getter body resulting in an improved combination of mechanical and gas-sorption properties.
