Abstract

Samples of superconducting ceramics of Bi2Sr2CaCu2O8+d have been elaborated starting from a mixture of Bi2O3, SrCO3, CaCO3 and CuO. Different ways of initial firing have been tested for samples with different starting composition. X Ray Diffraction Powder (XRD) and Scanning Electron Microscopy show that, depending from starting composition and initial way of firing, some final samples present a pure superconducting phase.
