Preparation of Bi(Pb)-Sr-Ca-Cu-O superconductor with nano Co 3O4 addition

Abstract

The effect of nano Co3O4 addition (0-0.05 wt%) on the Bi(Pb)-Sr-Ca-Cu-O (Bi-2223) precursor powder has been investigated in terms of X-ray diffraction, scanning electron microscopy and dc electrical resistivity. The samples were prepared by the conventional nitrate coprecipitation operation. The X-ray diffraction patterns of all the samples indicated the presence of large amount of Bi-2223 phase along with minor amount of Bi-2212 and Bi-2201 phases. The volume fraction was estimated from the intensities of Bi-2223, Bi-2212 and Bi-2201 phases. The sample with x=0.01 wt% of added Co 3O4 shows the highest volume fraction of Bi-2223 phase formed (71%) and the highest superconducting transition temperature, T C (∼102 K). Both the onset critical Tc(onset) and zero electrical resistivity Tc(R=0) were determined from the dc electrical resistivity which the temperature range 83-115 ±1K and 70-102 ±1K respectively.
