摘要：
A new simplified method of the synthesize for Bi-Pb-Sr-Ca-Cu-O superconductor was found through a conventional solid-state reaction. Samples have been prepared by mixing powders of Bi2O3, PbO, SrCO3, CaCO3 and CuO and short-term ((5+5) h) sintering at 1133 K. The samples have 91% high Tc 2223 phase in volume fraction and exhibit the zero resistance temperature of 105 K in the superconducting transition. It is stressed that our synthesis method offers high quality sample in high speed with great advantage on low cost.
