摘要：
The effects of hot pressing (HP) on the critical current density (J(c)) of Ag-clad Bi(2223) superconducting tapes were investigated in detail. Results show that temperature, percentage reduction and reduction rats have a crucial influence on J(c). At 77 K and 0 T, the best J(c) value of 2.25 x 10(4) A cm(-2) has been measured on the tapes with a percentage reduction of 20% after HP under a pressure of 200 MPa at 750 degrees C.
