Abstract : This patent application discloses a process for producing a superconductor wire by: (a) coating the inner surface of a steel tube with a thin layer of silver metal; (b) packing the tube with high temperature superconductor ceramic (HTSC) powder; (c) sealing the tube; (d) cold working the tube to reduce its diameter; and (e) etching or dissolving away the steel tube to leave a superconductor wire comprising the silver metal coating that was on the inner surface of the steel tube as a thin silver metal sheath which encapsulates the HTSC powder. The superconductor wire can be further treated by sintering or oxygenating the HTSC powder.
