Transport Properties of High Green Core Density Bi-2212 Textured-Powder Conductors

Bi-2212 monocore conductors have been fabricated using a high-density pre-textured Bi-2212 precursor. The conductors have been reacted using two methodologies: a non-melt (sintering) heat treatment, and a traditional partial-melt processing. Textured precursors are mechanically fabricated via a die stamping process that both textures and increases the density of the Bi-2212 component. The precursors were jacketed in Ag and successfully extruded and drawn without sausaging. Results of the fabrication process, critical current measurements (4.2 K, 5 T), and microstructure studies will be presented.
