PURPOSE:To obtain the subject superconductor having improved critical temperature by adding a specific amount of a CuBi2O4 compound to a molded article containing Bi, Pb, Sr, Ca, Cu and O as constituent elements and baking the mixture in an O-containing atmosphere at a specific temperature. CONSTITUTION:A molded article containing Bi, Pb, Sr, Ca, Cu and O as constituent elements is incorporated with 5-42wt.% of a CuBi2O4 compound and the article is baked in an O2-containing atmosphere to obtain the objective oxide superconductor having a critical temperature of >=100K. |
