  • Method of handling liquid non-ferrous metals with refractory material
    Patent number: 7449045
    Abstract: A method of handling liquid non-ferrous metals after smelting. The liquid metal is in contact with a solid refractory material, and in the absence of electrical currents passing through the liquid-metal-contacting surfaces. The solid material is Ti3SiC2. The liquid non-ferrous material can be aluminum or an aluminum alloy, magnesium or a magnesium alloy, or other non-ferrous materials as to which the Ti3SiC2 material is stable.
    Type: Grant
    Filed: August 14, 2006
    Date of Patent: November 11, 2008
    Assignees: Sandvik Intellectual Property AB, Drexel University
    Inventors: Mats Sundberg, Jan-Olof Olsson, Chet Popilowski

  • Resistance heating element for extreme temperatures
    Patent number: 6903313
    Abstract: An electrical resistance heating element operable at extremely high temperature, up 2300° C. when used in a vacuum or in a reducing atmosphere, and up to bout 1200° C. when used in an oxidizing atmosphere. The element is formed substantially from titanium silicon carbide (Ti3SiC2), which is readily workable to enable it to be produced in different forms. It also has a higher mechanical strength than that of graphite heating elements.
