A preparation method of bulk Y-Ba-Cu-O superconductors with high transport critical current density

摘要

A preparation method of bulk YBa₂Cu₃Ox superconductors with high transport critical current and critical current density (Jc), wherein x is 7 - , obtained by a modified melt-textured growth method. A continuous dc current carrying capacity exceeding 120 A with critical current density, Jc, higher than 37300 A/cm² at 77K has been obtained for the prepared superconductor.
