Abstract

The effect of adding of Bi1.80Pb1.33Sr1.87Ca2Cu3O2 seeds(the 37Å phase) to the polycrystalline and glassy Bi-(Pb)-Sr-Ca-Cu-O materials was studied using XRD and SEM. The seeding effect was observed at 835 °C, 855 °C, and 870 °C in several compositions. Adding pre-synthesized 37Å phase powder to a mixture of unreacted starting materials accelerates the formation of additional 37Å phase.
