| 总结: | The effect of nano SnO₂ particle addition on superconducting properties of YBa₂Cu₃0₇⸳₈(YBCO) ceramics was systematically studied. Samples were synthesized using a standard solid state reaction technique by adding nanoparticles SnO₂ up to 0.8 wt%. The phase formation for samples 0.0wt% and 0.2wt% was characterized by X-ray diffraction (XRD) using Rigaku X-Ray Diffractometer. The crystal lattice parameters were found are not change and the orthorhombicity still remained with addition of nano Sn02.With the increase of nano SnO₂ addition, the superconducting transition temperature determined by standard four-probe method measurement decreased to 70K for x = 0.8 wt%, then dropped sharply with higher nano SnO₂ concentration. Results are discussed in relation with decreasing Jc with as an amount of the nano SnO₂ added. The value of Jc are not enhanced in the superconductor YBCO with higher-level concentration (x>0.2wb %) in the addition of nano of Sn02 added to the samples. |
