Abstract:
A high temperature superconducting composite made by a process comprising the steps ofproviding a reticulated foam structure comprising a metal selected from the group consisting of silver, silver alloy, gold and gold alloy, the reticulated foam structure having continuous ligaments defining a plurality of continuous open cells, filling the continuous open cells of the reticulated foam structure with a high temperature superconducting ceramic oxide or precursor, compacting the filled structure, and heating the compacted structure to melt and/or texture the high temperature superconducting ceramic oxide or precursor to form a continuous region of high temperature superconducting ceramic oxide throughout the compacted structure, wherein the metal is selected to have a higher melting temperature than the melt/texture temperature of the superconducting ceramic oxide or precursor.
