Summary

A precursor powder of the composition bismuth(1.86)-lead(0.26)-strontium(1.96)-calcium(0.95)-copper(2.97)-oxygen(10) containing mainly bismuth-2223 phase was employed. Particular attention was devoted to the microstructural properties of the tapes subjected to rolling and subsequent heat treatment in one, two, and three steps, respectively. A sharp texturing gradient exists in the superconducting cores, and the repeated treatment leads to deterioration of the superconducting properties.
