Abstract

A nearly pure 110 K phase of the ceramic superconductor Bi_1.92Pb_0.38,0.3Sb_xSi₂Ca₂Cu_3.2O_10-δ was obtained by codecomposition of coprecipatated oxalate technique. These samples with Sb=0.1, Pb=0.38 had zero resistance temperature at 102 K. For those samples with Sb=0.3, Pb=0.3, T_co was equal to 90 K. Their magnetic susceptibility all dropped sharply at 110 K and it does not change at 80 K. X-ray diffraction revealed that there was no 80 K or 20 K phase but the 110 K and an unknown phase. This unknown phase itself is not superconducting above 77 K. The average composition of the unknown phase is given as Bi₃₂Pb₃Sb₇Sr₂₉Cu₇O_x.
