Abstract

To explore high Tc in Bi-Sr-Ca-Cu-O system, many different nominal compositions have been prepared by using the traditional solid state reactions and using the method of crystallizion from glass samples. The better results are as follows: single high-Tc phase and essentially single high-Tc phase have been obtained from Bi1.8Pb0.35Sr2Ca2Cu3O and Bi2Sr2Ca6Cu7O respectively, by solid reaction. Basically single hign-T phase material with nominal composition Bi2Sr2Ca3Cu4Oy has been produced by the method of crystallizion from glass samples. The relationship between the starting composition heat treatment, preparation methods and high Tce is briefly discussed.
