CERAMIC SHEET, MANUFACTURING METHOD FOR Bi2223 OXIDE SUPERCONDUCTIVE WIRE, AND Bi2223 OXIDE SUPERCONDUCTIVE WIRE

摘要

PPROBLEM TO BE SOLVED: To provide a heat-treating member for generating effective Bi vapor during heat treatment in order to manufacture a long Bi2223 oxide superconductive wire having a high critical current value, and to provide a manufacturing method for a Bi2223 oxide superconductive wire using the heat-treating member. PSOLUTION: In the manufacturing method for the Bi2223 oxide superconductive wire, a ceramic sheet for heat-treatment of the Bi2223 oxide superconductive wire, the ceramic sheet being formed with a binder made of a material vanishing through its gasifying by the heat-treatment, ceramic fibers and oxide including Bi, and a precursor Bi2223 oxide superconductive wire, are wound and heat-treated together.
