Abstract

Has conducted research related to the addition of Nd on formation 2212 phase of superconductor system BPSCCO : (Bi1.63Pb0.37) Sr1.6Ca2.25Cu3.15Oy + Ndx. The samples prepared by solid state reaction method with sintering temperature of 830 oC for 27 hours. XRD measurements revealed that the samples have shown the formation (Bi, Pb)-2212 phase with a good crystalinity (FWHM < 0.250). Provided that the volume fraction of (Bi, Pb)-2212 phase formed increases with increasing of addition of Nd. The highest volume fraction of 94.11% was obtained on the sample with the fraction of x = 0.050. The measurements of resistivity as a function of temperature with 4-point electrode method revealed that the samples have not shown the Tco, but it have shown Tcon-set ~ 81K. The addition of Nd does not have a significant influence on the Tcon-set.
