    Abstract:

    In terms of the ideal microstructure for Bi-2223 wires with high Ic performance, Bi-2223 volume fraction along with distributions of impurity phases and Bi-2223 grain alignment were reviewed. This chapter summarized the characteristics of the present available wires, which had over 95% of Bi-2223 volume fraction and the degree of texturing ~6°. The results showed that there were many issues to address for further improvement of microstructure, though the wire had high Ic, enough for the current application use.
