Abstract
The precipitation process of the superconducting phases from the rapidly-quenched glasses has been studied as a function of both heat-treatment temperature and time for the three main compositions in the Bi-Ca-Sr-Cu-O system: Bi2Ca2Sr2Cu3O x , BiCaSrCu2O x , and Bi2CaSr2Cu2O x . The temperature-time-transformation diagram for each composition has been constructed and a difference has been found between those for the former two compositions and that for the last one.Keywords
