METHOD OF PREPARING MgB2 SUPERCONDUCTING WIRE AND THE MgB2 SUPERCONDUCTING WIRE PREPARED THEREBY

摘要

Disclosed herein is a method of preparing a MgB₂ superconducting wire and the MgB₂ superconducting wire prepared thereby. The method comprising rolling a raw powder by using a powder rolling method. According to the method of the present invention has an effect of increasing an effective area where superconducting current can flow by improvement of the connectivity of a MgB₂ superconducting powder and achievement of high density through a powder rolling process, and maintaining an uniform current value even in a large length because of the improvement of the connectivity.
