PROCESS FOR PRODUCING SUPERCONDUCTING OXIDE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a process in which a superconducting material of a large area with improved properties is efficiently produced through pyrolysis of a metallic organic compound and thermal treatment formation of a superconducting substance.

SOLUTION: The process for producing a superconducting material having undergone epitaxial growth through the steps of (1) coating a support with a solution of an organic compound of a metal whose oxide forms a superconducting substance and drying the same, (2) preliminary firing for pyrolysis of the organic component of the organic compound of the metal and (3) principal firing for conversion to the superconducting substance, characterized in that between the step (1) and (2), at the time of laser beam irradiation, laser beam irradiation is carried out from the side opposite to the side coated with the solution of the organic compound of the metal for formation of the superconducting substance.
