摘要：

The phase stability of a YBCO type superconductor has been studied for different total gas pressures, oxygen partial pressures and temperatures by using a oxygen-hot-isostatic-process. A total gas pressure versus temperature phase diagram at constant oxygen partial pressure (10 MPa), and an oxygen partial pressure versus temperature phase diagram at constant total gas pressure (200 MPa) were obtained. The dependence of the phase transformation temperature of the YBCO type superconductor on the oxygen partial pressure and the total gas pressure was examined. The phase stability analysis reveals for the first time that the transformation temperature of this YBCO type superconductor depends on both the total gas pressure and the oxygen partial pressure.
