Abstract
A superconductive composite member, which has a core composed of an oxide ceramic material which is surrounded by an envelope, has an increased core density in order to achieve a higher critical current density. The increased core density is obtained during a hot-shaping step of the core material in the envelope, wherein the composite is heated to a temperature wherein the superconductor material is present in either a molten or a partially molten state.
