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