MANUFACTURE OF HIGH TEMPERATURE SUPERCONDUCTOR

摘要

PURPOSE:To manufacture a high temperature superconductor able to improve the critical current density while making the critical current density uniform along the longitudinal direction in a long wire. CONSTITUTION:In a manufacturing method involving the processes of heat treatment of powder prepared by applying heat treatment to an oxide superconductor or its raw material and then carrying out pulverization repeatedly several times, filling a metal pipe with the powder, carrying out plastic processing to make the resulting pipe like a tape, and carrying out heat treatment, the metal pipe is filled with the powder after heat treatment and sealed while preventing the powder from adsorbing a gas again.
