Abstract
We have developed a Melt Casting Process (MCP) as an alternative route for the preparation of Bi2Sr2CaCu2Ox. This process offers an access to a variety of different shapes and sizes interesting for applications in electrical engineering as e.g rods and tubes. The addition of SrSO4 significantly improves the reproducibility of the critical current densities, jc (H=0)=55000 A/cm2 (4 K) and 2200 A/cm2 (77 K). Large bulk parts exhibited more than 2000 A (77 K) in their self field. The pecularities of MCP allow the integration of noble metal current contacts with resistances below 1 µΩhm (77 K), even under high currents. First test of prototypes for applications in electrical engineering (rods and tubes for current leads, hollow cylinders for inductive current limiters) show promising results.
