摘要：

Ultrasonically prepared freeze-dried nitrate precursors and high-precision solution calorimetry were used to investigate the low-temperature thermodynamic stabilities of compounds in the Y-Cu-O, Ba-Cu-O, Y-Ba-O, and Y-Ba-Cu-O pseudobinary and pseudoternary systems at 1 atm of oxygen, Y2Cu2O5, Y2BaCuO5, and BaCuO2 were found to be metastable below 682 degrees, 728 degrees, and 710 degrees +/- 5 degrees C, respectively, The only stable phases in the Y-Ba-Cu-O system at 298 K and 1 atm of oxygen are Ba2Cu3O6, CuO, BaO2, and Y2O3. By compiling the calorimetric and phase equilibria data, a series of Y-Ba-Cu-O isothermal phase diagrams were constructed between 25 degrees and 900 degrees C at 1 atm of oxygen.
