摘要：

An unmixed 110 K phase of the Bi(Pb)-Sr-Ca-Cu-O superconductor was synthesized by annealing the sample with the nominal composition (Bi0.85Pb0.15)2 (Ca0.65Sr0.35)4.25Cu4.75Oy at 845°C for 50 hours. X-ray diffraction patterns indicate that the sample is basically equivalent to the so-called 2223 BSCCO phase. Magnetization data show a single superconducting transition of 110 K. With suitable amounts of Pb plus excess Ca and Cu instead of the ideal Bi2Sr2Ca2Cu3Oy, the 80 K or 2212 superconducting phase can be significantly decreased.
