A zero resistance transition temperature of 108 K has been achieved for Pb-doped Bi-Sr-Ca-Cu-O superconductors prepared by conventional powder solid-state reaction. The materials contained both the high Tc phase (Bi2Sr2Ca2Cu3Ox) and the low Tc phase (Bi2Sr2Ca1Cu2Ox). Critical current density at 100 K in a zero magnetic field was 3.5 A/cm2 which was larger than that of the Pb-free sample.
