  • Method for producing a porous titanium material article
    Patent number: 7175801
    Abstract: Method for producing a porous titanium material for example a support. Starting from a titanium powder this powder is sintered under vacuum conditions in an inert/reducing atmosphere. Titanium hydride is added as powder and decomposes during sintering. The hydride ions provide a very reducing atmosphere preventing any titanium oxide or carbide/nitride composition to be formed at elevated temperature.
    Type: Grant
    Filed: May 5, 2003
    Date of Patent: February 13, 2007
    Assignee: Stichting Energieonderzoek Centrum Nederland
    Inventors: Zbigniew Rak, Louis David Berkeveld, Gerrit Snijders
