   Abstract : Basic bulk high temperature superconductors in the Bi-Sr-Ca-Cu-O system and the BiPb-Sr-Ca-Cu-O system were prepared through the solid state reaction route and the coprecipitation method. The formation of 110 K phase promoted by partial Pb substitution for Bi was studied. Effects of heat treatment on 110K phase formation were studied. READ MORE
