By using the CT-OP (Controlled Over-Pressure) sintering furnace, Sumitomo Electric (SEI) succeeded in improving various characteristics such as critical current and mechanical properties of Ag sheath Bi-2223 wire commercialized as DI-BSCCO. Recently, SEI has developed and commercialized high strength DI-BSCCO Type HT-NX wire reinforced with the Ni alloy tapes and has applied the residual axial compression after lamination. The critical tensile stress of Type HT-NX has reached 400 MPa at 77 K. For high field magnetic application such as NMR using Bi-2223 based superconducting wire reinforced with Ni alloy tapes is highly expected.
