Effects of Y (Yttrium) Addition on Second Type Bscco Superconductors

In this study, the effects of Y (Yttrium) addition on the structural and magnetic properties of theBi2Sr2Ca1-xYxCu2O8 (x = 0.0, 0.05, 0.075, 0.1, 0.15 and 0.20) superconductors that were prepared by sol-gel methodwere investigated. Energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), X-raydiffraction (XRD) and alternating current magnetic susceptibility measurements performed for the superconductingsamples with partial substitution of Y element instead of Ca element. The XRD results showed that the mainphase was independent of the Y concentration of the Bi- (2212) phase, according to from the energy-dispersivespectroscopic measurements samples were formed desired compositional values and the SEM results showed thatthe microstructures of the samples destroyed by increasing the Y-amount. The results of AC magnetic susceptibilitymeasurements showed that the critical temperature values decreased with increasing Y contribution.
