We report the NdBa2Cu3Oy (Nd123)-Ba3Cu5Oz(035) pseudo-binary section in the Nd2O3-BaO-CuO system under the oxygen partial pressure pO2 = 0.01 atm. We performed thermogravitational and differential thermal analysis (TG-DTA) and powder x-ray diffraction (XRD) measurements for quenched samples. We also performed high-temperature XRD for the determination of equilibrium solid phases at elevated temperatures. In situ observation of the primary solid phases with laser scanning microscopy was also performed for an accurate determination of the liquidus line. In comparison with the Nd123-035 pseudo-binary phase diagram in air, the liquidus line under pO2 = 0.01 atm shifts to a lower temperature.
