METHOD OF MANUFACTURING MAGNESIUM DIBORIDE SUPERCONDUCTING BULK MAGNET, AND MAGNESIUM DIBORIDE SUPERCONDUCTING BULK MAGNET |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a MgB<SB POS="POST">2</SB>superconducting bulk magnet for using, as a bulk magnet rather than wiring material, MgB<SB POS="POST">2</SB>having an excellent superconducting performance and holding a considerable promise for application for a strong coil magnet, and to provide a MgB<SB POS="POST">2</SB>superconducting bulk magnet manufactured according to the method. <P>SOLUTION: The method of manufacturing a MgB<SB POS="POST">2</SB>superconducting bulk magnet comprises: a raw material powder preparing step for preparing raw material powder consisting of a mixture of boron-containing powder having a particle size of 10 μm or smaller, and magnesium-containing powder; a bulk mold step for molding the raw material powder prepared in the raw material powder preparing step into an appropriate form of bulk; a heat treatment step for performing a heat treatment on the bulk formed in the bulk mold step; and a magnetizing step for magnetizing the bulk after the heat treatment step to make the bulk a magnet. <P>COPYRIGHT: (C)2012,JPO&INPIT |
