PRODUCTION OF RARE EARTH-BARIUM-CUPRATE-BASED SUPERCONDUCTOR

Japanese Patent JPH1112094

A

PROBLEM TO BE SOLVED: To provide a method for producing rare earth-barium-cuprate superconductor by melting and organizing a superconductive material on a metal substrate. SOLUTION: A mixture of a rare earth-barium-cuprate seed crystal having a high melting point with a rare earth-barium-cuprate powder having a melting point lower than that thereof is supported on a metal substrate, and the materials supported on the substrate is subjected to a heat treatment at the temperature lower than the melting point of the high melting point rare earth- barium-cuprate seed crystal and the metal substrate and higher than the melting point of the lower melting point powder. The treated and supported material is cooled to the temperature lower than the melting point of the supported material to provide the objective rare earth-barium-cuprate-based superconductor in a thick film shape on a metal tape or a metal wire, or a powder in a tube in the method for producing the rare earth-barium-cuprate-based superconductor.
