ABSTRACT:
A method for fabricating a ceramic superconductor comprising the following steps: mixing a copper or copper alloy metal, a first metal oxide or carbonate which includes one element selected from group IIA of the Chemical Periodic Table, and a second metal oxide or carbonate which includes one element selected from group IIIB of the Chemical Periodic Table to form a copper/ceramic mixture; heting a copper/ceramic mixture to a temperature in the range between 900.degree.-1100.degree. C.; and cooling the heated copper/ceramic mixture slowly, thereby forming a superconductive material. The copper/ceramic mixture may be extruded through a die prior to the heating step, thereby forming a superconductor of desired shape.
