Increase in critical temperature of superconductors is a major area of research. We have used ceramic technique
in order to synthesize high Tc conductors. We have also studied the temperature dependence of the electrical
resistivity of high-Tc Bismuth based superconductors. These superconductors have been prepared from the
materials Bismuth Oxide (Bi2O3), Lead Oxide (PbO), Strontium Carbonate (SrCO3), Calcium Carbonate (CaCO3),
Barium Oxide (BaO) and Copper Oxide (CuO) with conventional solid state reaction using general formula
Bi2Sr2Can-1CunO2n+4+δ. The structural properties of the samples were investigated through X-ray diffraction
analysis performed at room temperature. Electrical resistivity has been measured using four probe method. The
critical temperature of the Bi-based superconductors has been found to be 100 K.
