摘要：

The phase diagrams for the binary and ternary Nd2O3-CuO and (0.85Nd2O3-0.3CeO2)-CuO systems are reported and the eutectic points and the liquid lines are determined. We have also explored the crystal growth from molten solutions of compositions 70% CuO-(30-z)% Nd2O3-z% CeO2 for a range of CeO2 concentrations. We show that the composition of the crystals is not uniform for a given z value but the compositional range appears to be quite narrow (x=0.17(3)) for z=3.6. This concentration produces also the largest crystals (≈10 X 10 X 0.3 mm3). © 1990.
