Abstract

CaCuO₂ content-has been optimized for two-powder process. The experimental results indicate that as precursor powders have 5% excessive CaCuO₂; the critical current density of tape increases about 10%. During the reaction process, excessive CaCuO₂ afford enough liquid phase which accelerate the 2223 phase formation, but too much CaCuO₂(>15%) will produce impure phases at grain boundary. Large impurity particles decrease the texture degree of the 2223 phase and critical current density of the tape.
