Studying the Partial Substitution of (Pb) instead of (Bi) for superconducting compound Bi2-xPbxBa2Can-1CunO6+δ.

Abstract

The present study the partial substitution of Bismuth (Bi) instead of lead (Pb) for (Bi2-xPbxBa2Can-1CunO6+δ) superconducting compound Where (X=0,0.05,0.1,0.15,0.2) Samples were prepared by solid state reaction method with sintering temperature 750C0 for 48h Then the samples were cooled to room temperature at the same heating rate. To determine the critical temperature, the XRD analyses for all superconductor specimens was found that the crystal structure was for all specimens were (Orthorhombic structure).
