摘要：

The YBa2Cu3O7 phase was examined by high-temperature X-ray diffraction below 800-degrees-C at a series of O2 pressures between 1 and 10(-4) atm. The orthorhombic-tetragonal phase transition occurred at d approximately 0.5 in YBa2Cu3O7-d regardless of temperature and oxygen pressure, where the oxygen deficit, d, was decided using the nonstoichiometry data.
