摘要：

In this paper, we report a critical current density (J(c)) value >10(5) A/cm(2) at 77 K in short-length (approximate to 5-cm) Bi-2223 tapes made by the Ag-wire-in-tube method, in which an Ag wire was introduced into the Ag tube, The Ag wire extended along the entire length of the tape. At 77 K and in self-field, a maximum J(c) of 2 x 10(5) A/cm(2) was measured after three uniaxial pressing and heat treatment cycles, We also analyzed the transport properties of Ag-clad Bi-2223 tapes as a function of cooling rate. Maximum critical current values were two or three times higher for slow-cooled tapes than for fast-cooled tapes.
