Bi-2223 volume fraction and the critical current (I/sub C/) in Bi-2223/Ag tapes exhibited maximum values (f/sub 2223 max/ and I/sub Cmax/) versus sintering time; on further heating the Bi-2223 phase decomposed and the I/sub C/ decreased. The total ti

Samples of multifilamentary Bi-2223/Ag/alloy twisted filament tapes and Z stack round wires, consisting of untwisted and twisted stacks (or z-arrays) of flat filaments have been prepared. It was found that twist pitches of less than 10 mm may be inco
