摘要：

Phase-diagram data for the cuprate superconductors have become available only slowly owing to specific problems such as sluggish equilibration reactions. The phase relations of the system Y2O3-BaO-CuO(x) show that only BaCuO2-CuO melts can be used as solvents for the crystal growth of YBCO from high-temperature solutions. Data on the Bi- and Tl-cuprate superconductors are not available. The system (La,Sr)2CuO4-CuO(x) indicates a simple eutectic and high solubility of the superconductor, which therefore can be grown as large crystals.
