Description

This paper reviews overpressure (OP) processing of Ag-sheathed (Bi,Pb)2Sr2Ca2Cu3Ox (2223) flat wire. OP processing is a variant of hot isostatic pressing that densifies the 2223 filaments, which increases the critical current density Jc of the wire. OP processing is done at pressures up to 300 bar with a mixed Ar /O2 atmosphere in which the oxygen partial pressure is set so the 2223 phase is stable. The Ar pressure compresses the wire. The highest reported Jc in OP-processed short wires is 69.6 kA cm-2 (self-field (SF), 77 K) and 30.8 kA cm-2 (0.1 T, 77 K). Ic as high as 100 A has been achieved in 1.5 km lengths of OP wire
