摘要：

The phase equilibria of YBa2Cu3O7-d (123 phase) strongly influence its oxygen content and consequently its critical temperature T(c). With increasing content of BaCuO2 or CuO, T(c) decreases. Whereas, if Y2BaCuO5 (211 phase) is in equilibrium with the 123 phase, the oxygen content and T(c) of which is high. Bi2+x(Sr,Ca)3Cu2O8+d exhibits an extended single phase region and its T(c) is strongly affected by its chemical composition. In addition, the oxygen content of the phase is a function of the temperature and influences the T(c) of the phase.
