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.
