Resumen:
The equilibrium PO2 at 1023 K has been measured by means of ahigh sensitivity thermogravimetric equipment. The stability rangeof the 2212 superconducting phase at 1023 K as a function of PO 2was found to be 7.915 _< y _< 7.938 and 9.91.10 .4 < PO2 -< 1 atm. Fora PO 2 lower than 9.91.10 .4 atm. the sample decomposes. Variationof the Tc as a function of the oxygen content are only observedwithin the homogeneity range of the 2212 phase.
