Title:
METHOD FOR MANUFACTURING MAGNESIUM DIBORIDE SUPERCONDUCTIVE WIRE, AND MAGNESIUM DIBORIDE SUPERCONDUCTIVE WIRE MANUFACTURED USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/155659
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing magnesium diboride superconductive wire, to the magnesium diboride superconductive wire manufactured using same, and particularly, to a method for manufacturing magnesium diboride superconductive wire by rolling the magnesium diboride raw material powder by using a powder rolling method, wherein the density and connectivity of superconductive powder introduced into a metal coating material can be increased, and accordingly, the actual effective area through which superconductive current can flow may be enlarged. In addition, the manufacturing method of the present invention is advantageous in terms of manufacturing cost and manufacturing speed since the final size of the wire is achieved almost at the onset of processing by employing a powder rolling process. Moreover, the method of the present invention is advantageous in that it can be applied to processes in which various doping materials that function as a flux pinning center are added in order to improve the properties of the flux pinning center of a magnesium diboride superconductive wire under a magnetic field.
