  • Yttria-based refractory composition
    Patent number: 8372769
    Abstract: Method for producing a mold for use in casting reactive metals comprising preparing a slurry of a yttria-based refractory composition and a binder, and using said slurry as a mold facecoat by applying said slurry onto a surface of a mold pattern, wherein said yttria-based refractory composition is obtainable by (a) mixing particles of a yttria-based ceramic material and a fluorine containing dopant, and (b) heating the resulting mixture to effect fluorine-doping of said yttria-based ceramic material.
    Type: Grant
    Filed: May 24, 2011
    Date of Patent: February 12, 2013
    Assignee: Treibacher Industrie AG
    Inventors: Peter Janz, Sigrun Tauber
