The highTc superconductor of nominal composition Bi1·5-Pb0·5-Ca2-Sr2-Cu3-Ox was prepared by solid-state reaction method. The upper critical fieldHc2 of the material with a zero-resistance transition at 110K was investigated by observing variations in resistance with temperature down to 90 K and with a magnetic field up to7T. The slope ofHc2 with temperature was about −0·41T/K for zero resistance transition and −6·86T/K for onset of superconductivity.Hc2 values at 0K were estimated to be 31·3T and 563T for zero-resistance transition and onset of superconductivity respectively.
