Abstract, Filamentary and sheet-like oxide superconductive bodies can be produced by ceramic fabrication techniques such as extrusion screen printing, tape casting and slip casting, provided the bring conditions are chosen such that the correct amount of oxygen deficiency is attained in the ceramic, and such that contact with chemically non-compatible material is avoided. Thus produced superconductive bodies are advantageously incorporated into apparatus such as magnets power cables, interconnects, electrical components, and sensors.
