Abstract
A ceramic superconductivity part, such as a wire 10, is produced through the partial oxidation of a specially formulated copper alloy in a core 12. The alloys contain low level quantities of rare earth and alkaline earth dopant elements. Upon oxidation at high temperature, superconducting oxide phases are formed as a thin film 14.
