  • Composite ceramic body and method for producing the same
    Patent number: 7179532
    Abstract: A composite ceramic body includes a fiber-reinforced core region containing carbon, and a surface region containing SiC. In order to produce a composite ceramic body having good long-term behavior, the proportion of SiC contained in the body varies continuously, or essentially continuously, from inside the core region towards the surface region.
    Type: Grant
    Filed: March 24, 2003
    Date of Patent: February 20, 2007
    Assignee: Schunk Kohlenstofftechnik GmbH
    Inventors: Marco Ebert, Martin Henrich, Dietrich Kehr, Thorsten Scheibel, Roland Weiss

  • Process for the production of a flexible superconductor
    Patent number: 4299861
    Abstract: A process for the production of a flexible superconductor comprising a carbon fiber having thereon a layer of niobium carbonitride, and an outer layer of a highly conductive metal. Initially, niobium is deposited on the fiber, and the niobium-coated fiber is then exposed to gaseous sources of carbon and nitrogen while the temperature is subsequently raised.
