Preparing method of MgB2 superconducting conductor and MgB2 superconducting conductor prepared thereby

摘要

The invention Pung Yi small magnesium production process and thus Pung Yi superconducting wire is produced by small magnesium in the superconducting wire Specifically, according to Pung Yi by providing a method of manufacturing a superconducting wire of magnesium Pung Yi cattle, characterized by rolling a predetermined raw material powder with magnesium powder rolling method, it is possible to improve the density and connectivity of the superconducting powder filled in the inside metal coating material , has the effect of substantially increasing the effective surface area that superconducting current can flow through them. In addition, the production method of the present invention may have advantageous effects in the production cost and production speed, starting a step closer to the final size of the wire through the powder rolling step, and further the magnetic field and magnetic flux Pung Yi to increase the flux of the predetermined fixed characteristic magnesium superconducting wire in the step of adding a variety of doping material to the fixing point there is an advantage in that role can be applied to the present invention. ;
