The superconducting Bi (Pb)-Sr-Ca-Cu-O system, with the high-Tยข phase, was prepared by the modified citrate process using an aqueous solution of metal nitrate containing citric acid and tartaric acid. It was found that transparent sols were obtained from the solution of initial pH of 7.6-9 and a mol
