摘要：

The oxygen content of Bi2+xSr3-yCaCu2O8+y (2212 phase) has been determined as a function of its cation concentration. With increasing Ca and Bi content the oxygen content increases and T(C) decreases. The oxygen content of Ca rich 2212 phase increases with decreasing annealing temperatures. The study shows that the T(c) of the 2212 phase primarily is controlled by its cation concentration.
