摘要：
A high-Tc oxide superconductor including Bi, Sr, Ca, Cu, O and at least one of Pb and Al, with a high critical temperature than that of liquid nitrogen. A method for producing the high-Tc oxide superconductor is also disclosed, in which Bi₂O₃, SrCO₃, CaCO₃, CuO and PbO or Al₂O₃ powders are mixed calcined, ground, cold-pressed and sintered. The calcined mixture may be melted and annealed to obtain a tape-form superconductor.
