摘要：

The subsolidus phase relationship in the Nd-Ba-Cu-O system has been investigated at 890-degrees-C in air. In this study, the discrepancies in the published phase diagrams of this system have been clarified. For the BaO-rich region, CO2-free (CO2 < 3 ppm) air was necessary to synthesize equilibrium phases. Significant results include determination of the solubility limits of 0.04 less-than-or-equal-to x less-than-or-equal-to 0.6 in Nd1+xBa2-xCu3O7+delta, the existence of a Nd2BaCuO10 solid solution, and discovery of a new phase, NdBa6Cu3Oy, in the BaO-rich region.
