  • High temperature superconducting ceramic oxide composite with reticulated metal foam
    Patent number: 6700067
    Abstract: A high temperature superconducting composite rod, wire or tape is formed by filling the open cells of a reticulated foam structure made of silver, silver alloy, gold or gold alloy with a superconducting ceramic oxide or precursor, compacting the filled structure and forming it into a rod, wire or tape and heating it to melt and/or texture the superconducting ceramic oxide. The resulting composite has continuous ligaments of metal throughout a continuous region of superconducting ceramic oxide.
