摘要：
Bismuth family high-temperature superconducting samples with varying initial Pb, Sr and Ca stoichiometries have been prepared using a polymer solution synthesis method. These samples have been characterized by powder X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy and magnetic ac susceptibility. The samples which yield the highest percentage of 2223 phase have in common an excess amount of Pb and a deficiency in Sr. The sample with best intragranular properties has a stoichiometry represented by Bi1.8Pb0.35Sr1.87Ca2.1Cu3O10+delta. It is also shown that, in contrast with the intragranular properties, the intergranular properties are irreproducible in almost all the samples studied.
