ABSTRACT:
A preparation method of bulk YBa.sub.2 Cu.sub.3 O.sub.x superconductors with high transport critical current and critical current density (Jc), wherein x is 7-.delta., 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/cm.sup.2 at 77K has been obtained for the prepared superconductor.
