Abstract
A pre-existing superconductor ceramic which is bonded to a substrate is passed through a relatively short heating zone to melt the ceramic superconductor. As the superconductor is subsequently cooled after it has passed through the heating zone, a temperature gradient is established along the superconductor which causes the melted crystals to renucleate and grow along and parallel to the temperature gradient. The resulting crystalline structure exhibits improved superconducting properties when the superconductor is placed in the presence of a magnetic field. For appropriate applications, the substrate can be formed as a wire.
