  • Method of producing nanophase W powder by low-pressure vapor phase reaction
    Patent number: 7208028
    Abstract: W powder is produced by: preparing a precursor containing tungsten; producing gas by vaporizing or sublimating the precursor; separating the tungsten component by placing the gas in an inert atmosphere while maintaining pressure below atmospheric pressure; and condensing the tungsten component at pressure below atmospheric pressure.
    Type: Grant
    Filed: December 30, 2003
    Date of Patent: April 24, 2007
    Assignee: Korean Institute of Machinery and Materials
    Inventors: Byung Kee Kim, Jin Chun Kim
