Oxide superconductor and method of manufacturing the same |
| 摘要 |
The oxide superconductor according to the present invention is represented by (Hg1-xPbx)Ba2Ca2Cu3O delta (0.08 </= x </= 0.41, 7.625 </= delta </= 9.15), and has a crystal structure in which a lamination unit of (Hg, Pb)Oz-BaO-CuO2-Ca-CuO2-Ca-CuO2-BaO is laminated in a c-axial direction of the crystal structure (0.625 </= z </= 2.15). Further, the method of manufacturing an oxide superconductor, according to the present invention, includes the steps of: mixing material powders of HgO, PbO, BaO, CaO and CuO at a mole ratio of (Hg1-xPbx):Ba:Ca:Cu = a:2:b:c (1 </= a </= 2.5, 2 </= b </= 3, 2.5 </= c </= 4) and compression-molding the mixture powder into a compact; and subjecting the compact to a thermal treatment at 600-750 DEG C. |
