Narrow range of zinc oxide core–shell hollow microspheres dopings for mechanical tensile promotion of 110KBPSCCO superconductor

Abstract

Although substitutions on copper sites always inhibit superconducting properties, the present investigations were successfully promoted mechanical tensile averages for HTc-2223- BPSCCO superconductor with general formula BiPbSr2Ca2Cu3-x(Zn)xO10±δ where x = 0.02, 0.04,0.08 and 0.16 mol respectively in the investigated range without damaging its superconducting features. The study is focusing on the effect of core-shell zinc ions hollow microspheres dopings (x) on the copper sites, where 0 ≤ x ≤ 0.16 mol on the superconducting, mechanical tensile features of 110K-2223-BPSCCO superconductor. The structural and micro-structural features of pure and core shell Zn-doped BPSCCO superconductors samples were carefully investigated by x-ray diffraction (XRD) and scanning electron microscope (SEM). Mechanical tensile measurement indicated that doping ratio (x) with ~0.08 mol is the optimum doping ratio from core shell hollow zinc microspheres achieving maximum tensile average of 51.2 MPa with stroke~0.323 mm acheiving promotion ratio~63.57% in contrast with mechanical tensile measured for pure 2223- BPSCCO superconductor (31.3 MPa with stroke~0.172 mm).
