Fabrication and properties of some Ag-alloy sheathed Bi-2223 tapes

Mono and multifilamentary powder-in-tube tapes with sheaths of Ag, AgCu/sub 0.02/, Ag(AgCu/sub 0.02/), AgAl/sub 0.25/, Ag(AgAl/sub 0.25/), AgNi/sub 0.25/Mg/sub 0.25/, AgTi/sub 0.25/Mg/sub 0.25/, and AgTi/sub 0.25/ alloys have been fabricated and their physio-chemical properties and effect on the phase formation of Bi-2223 determined. Alloying was found to have a significant effect on phase formation of the Bi-2223 phase formation linked to the alloying elements reactive to oxygen, Cu
