Abstract

A nearly pure 110 K phase of the ceramic superconductor Bi1.92Pb0.38,0.3SbxSi2Ca2Cu3.2O10-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, Tco 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 Bi32Pb3Sb7Sr29Cu7Ox.
