  • Method of producing alloy powders, alloy powders obtained by said method and products applying said powders
    Publication number: 20030094076
    Abstract: This invention aims at providing a method of obtaining fine alloy powders, which are extremely small in particle size, high in purity, and uniform in composition, providing fine alloy powders obtained by this method, and providing molding materials, slurries, and electromagnetic shielding materials, which use these fine alloy powders. This invention provides a fine alloy powder production method, which is characterized in that after performing the process of mixing at least a trivalent titanium compound and a complexing agent, which binds with the trivalent titanium ion, in an aqueous solution containing two or more types of metal ion, the two or more types of metal are made to deposit simultaneously.
    Type: Application
    Filed: January 13, 2003
    Publication date: May 22, 2003
    Applicant: Sumitomo Electric Industries, Ltd.
    Inventors: Akihisa Hosoe, Shinji Inazawa, Masatoshi Majima, Katsuya Yamada, Hiroshi Okazaki, Souji Nishikawa, Toshio Shimotsuji
