  • Structure and method of application for protecting the superconductivity of superconducting composites
    Publication number: 20040023079
    Abstract: A structural arrangement of superconducting composites is provided to protect their superconductivity in such a way that these composites are electrically connected in a certain manner. The invention may be practiced with any desired superconducting material, and bismuth based superconducting materials are preferred. The shape and size of the superconducting composites may vary.

  • Method of fabricating fine high temperature superconducting composites
    Publication number: 20030130128
    Abstract: A superconducting composite is fabricated by coating a wire or tape substrate with fine superconducting precursor powders followed by a sintering operation. A superconductor may also be prepared by further rolling. Several superconducting composites may be twisted together to obtain a multi-filamentary wire and sheathed by a silver foil or tube, at least partly open along the length.
