摘　　要：There are at least three superconducting phases in the Bi-Sr-Ca-Cu-O system, Bi₂Sr₂CuO_x （2201 phase）, Bi₂Sr₂CaCu₂O_y （2212 phase） and Bi₂Sr₂Ca₂Cu₃O_z （2223 phase ）. At present, the high temperature behavior of superconducting phases has not been reported in detail. In fact, the melting process plays an important role in improving J_c in oxide superconducting materials. For Bi-system, therefore, the study on high temperature behavior of the superconducting phases is important for increasing the J_c values.
