We have melt-processed a series of Ag-sheathed tapes with compositions ranging from 2.18 - 2.0:2:1:1.9 - 2.0 (Bi:Sr:Ca:Cu) in 100% ( atm). These compositions were chosen since changing the Bi and Cu content varied the volume fraction of and in the melt, which affected their volume fraction in fully processed tape. The composition 2.1:2:1:1.95 yielded the most homogeneous, highly aligned microstructure in fully processed tape and also had the highest .
