Abstract
Superconducting Bismuth-oxides with three superconducting phases (Bi-2201, Bi-2212, and Bi-2223) are one kind of important high temperature superconductors and efforts abound on the mechanisms of the three phase developments. Up to now, researchers have just concentrated on mechanisms of individual phase development, not on the relationships among three phases during phase development. To reveal the connection between reported mechanisms, time dependence experiemnts were performed in this study. Superconductors in experiments were sintered at different time and contents of the three superconducting phases were determined by analysis of X-ray diffraction. On the other hand, time dependence models were suggested, which expressed processes of crystal developing and decomposing for the three phases at high temperature. The suggested models introduced time concept and combined the reported mechanisms into one. Furthermore, with suggested models we derived relevant formulae that could quantitatively express developing and decomposing for these three phases. The theoretical predicts calculated from the introduced formulae were in agreement with experimental data. Therefore, the suggested models were supported by experimental results.
