Abstract :
The prepared Superconducting samples achieved by a method of solid-state reaction and methodically
deliberate for their superconducting properties. Preparation methods of the Bi1.7Pb0.3NdxSr2Ca2Cu3O10 +Ϩ
compositions with addition of Nd with particle size 50 nm, with (0.1≤x≤0.6) wt %. Studying the Nd nanoparticles
effect on the physical properties of superconducting phase. The explored of phase structural characteristics of
samples through powder X-ray diffractometer, reveals that all the samples crystallize in orthorhombic structure.
Also, phase examination by XRD indicated that Nd nanoparticles enhanced the (Bi, Pb)-2223 phase formation. The
method of DC four-probe was used to measure the critical transition temperature (Tc) and found to have maximum
value at x=0.2 wt % sample.
