Abstract
A ceramic superconductor comprises a substantially nonmagnetic preannealed nickel-based alloy substrate which supports a ceramic superconductor. The substrate may include aluminum to strengthen the substrate and make it less magnetic. The substrate is substantially devoid of minority constitutent oxide shell formers and the ceramic is formed on the substrate by sintering superconductor grains at temperatures above 1000.degree. C. to enhance densification of the ceramic.
