METHOD FOR MANUFACTURING RE123 SUPERCONDUCTIVE THIN-FILM TAPE WIRE ROD AND RE123 SUPERCONDUCTIVE THIN-FILM TAPE WIRE ROD

摘要

PROBLEM TO BE SOLVED: To provide a heat treatment method for orienting superconductive crystal of the whole superconductive layer to a high degree, i.e., a method for manufacturing an RE123 superconductive thin-film tape wire rod having a high critical current value.SOLUTION: A method for manufacturing an RE123 superconductive thin-film tape wire rod comprises: an intermediate layer forming step of forming an intermediate layer on a metal substrate; a precursor forming step of forming a precursor wire rod by applying a raw material onto the intermediate layer; and a thin film forming step of heating the precursor wire rod to form an RE123 superconductive thin film. The thin film forming step heats the metal substrate in an induction heating method to transfer heat from the metal substrate side to the raw material side.
