Growth of superconductor material in a fluxed melt, and article of manufacture

摘要

A bismuth-strontium calcium cuprate material shows commercial promise as a high-Tc superconductor material, means are desired for producing such (as well as isostructural) superconductor material in the form of macroscopic single-crystal bodies. The invention provides for the growth of such bodies from a fluxed melt, in bulk or epitaxially on a substrate, the fluxing agent being chosen to include sodium chloride, potassium chloride, or a mixture of sodium chloride and potassium chloride.
