Abstract
A process for producing Bi-2223 high T,superconductor in which fine MgO particles (<0.1 &mgr;m) are homogeneously distributed to provide flux pinning centers in Bi-2223 high T,superconductor in order to give enhanced critical current density under magnetic field, as compared to the Bi-2223 high T,superconductor without MgO dispersion, when processed under similar conditions. The process comprises mixing partially converted Bi-2223 powder and MgO fine particles, drying to give mixed powder, filling in silver tube, drawing, rolling and heat-treating at a temperature and for a time sufficient to form Bi-2223 high T,superconductor in which fine MgO particles are homogeneously distributed.
