Change of superconducting, electrical, structural and mechanical characteristics belonging to Bi-2223 superconducting materials doped by ZrO2

In this study; the effect of ZrO2 doping on the properties superconducters Bi-2223. The samples were prepared by solid state reaction method. This exhaustive study experimentally deals with the role of the Zr foreign impurities on the microstructural, electrical and superconducting properties pertaining to the bulk Bi-2223 superconducting compounds by means of the typical experimental characterization methods regarding bulk density, dc resistivity (ρ-T), transport critical current density (Jc), X-ray powder diffraction (XRD), electron dispersive X-ray (EDX), scanning electron microscopy (SEM) and Vickers microhardness (Hv) surveys.
