  • Graphite electrode
    Patent number: 9497804
    Abstract: A graphite electrode exhibits oxidation resistance by modifying the outer radial surface characteristics. The outer radial surface may be modified by providing a textured portion which improves water flow while minimizing water absorbtion. Alternately, a layer of flexible graphite or plurality of particles of exfoliated graphite may be disposed on the outer radial surface of the electrode body.
    Type: Grant
    Filed: June 29, 2011
    Date of Patent: November 15, 2016
    Assignee: GrafTech International Holdings Inc.
    Inventors: Philip D. Coleman, Greg E. Murray, Marco Napolitano, Aaron Tomasek, Brian Bowman, Daniel W. Krassowski, Michael Frastaci
