摘要：

The equilibrium P(O2) at 1023 K has been measured by means of a high sensitivity thermogravimetric equipment. The stability range of the 2212 superconducting phase at 1023 K as a function of P(O2) was found to be 7.915 less-than-or-equal-to y less-than-or-equal-to 7.938 and 9.91.10(-4) less-than-or-equal-to P(O2) less-than-or-equal-to 1 atm. For a P(O2) lower than 9.91.10(-4) atm. the sample decomposes. Variation of the T(c) as a function of the oxygen content are only observed within the homogeneity range of the 2212 phase.
