Abstract: Enhancement of Phase Formation and Critical Current Density in (Bi,Pb)-2223 Superconductor by Boron Addition and Ball Milling

Abstract
The effects of crystalline boron addition and ball milling on the phase formation and transport properties of (Bi,Pb)-2223 HTS have been studied. Samples with nominal composition Bi_1.7Pb_0.3Sr₂Ca₂Cu₃B_xO_y, x=0 - 0.5, were prepared via a solid state reaction route. Superconducting properties of undoped (reference) and boron-added (Bi,Pb)-2223 compounds were investigated through X-ray diffraction (XRD), scanning electron microscopy (SEM), resistivity and transport critical current density (J_c) measurements. Obtained results have shown that boron additive leads to the acceleration of high-T_c phase formation and enhancement of J_c in (Bi,Pb)-2223 superconductor. The estimated volume fraction of (Bi,Pb)-2223 phase increases from ~25 % for reference specimen to ~75 % for x=0.15. Moreover, strong increase in the J_c was observed for the x=0.15 sample (J_c=340 A/cm²), compared to a reference sample (J_c=115 A/cm²). We have studied the effect of high-energy ball milling on J_c in reference and x=0.15 samples. Addition of B in combination with the ball milling leads to the further enhancement of J_c up to 490 A/cm², whereas the ball milling of reference specimen causes the marked decrease in both J_cand T_c values. Improvement of superconducting properties in (Bi,Pb)-2223 superconductor can be attributed to the acceleration of high-T_c phase formation along with the enhancement of intergrain coupling due to the elemental boron addition.
