摘要：
The Pb solubility of the 2212 and 2223 phase has been determined as a function of the temperature, and phase relations within the quasiquinary system Bi2O3-PbO-SrO-CaO-CuO with emphasis on the high-temperature superconducting compounds 2212 and 2223 have been obtained. The Pb solubility exhibits a distinct maximum at about 860-degrees-C and 840-degrees-C for the 2212 and 2223 phase, respectively. With increasing and decreasing temperature the Pb content of both phases decreases resulting in a change of the content of the superconducting phases. The Pb content of the 2223 phase has no influence on the T(c) of the phase.
