A high-Tc, superconductor with a nominal composition of Bi1.6Pb0.4Sr2.0Ca2.0Cu3.0Oy, was prepared by the polymer gel method. The precursor gel was produced by the reaction of metal nitrates with a stoichiometric amount of poly (acrylic acid) (PAA) in ethylene glycol (EG) or poly (ethylene glycol) (P...
