    abstract = {The aim of this study is to investigate phase equilibria in the ZrO<SUB>2</SUB>-Nd<SUB>2</SUB>O<SUB>3</SUB>-Y<SUB>2</SUB>O<SUB>3</SUB> System in the temperature range 1250-1600&deg;C for the Nd<SUB>2</SUB>O<SUB>3</SUB> rich compositions and to study transformations of three phase assemblage consisting of the Nd<SUB>2</SUB>O<SUB>3</SUB> hexagonal phase A, monoclinic phase B and pyrochlore under increasing temperature. The samples were characterized by means of X-Ray Diffraction (XRD), Scanning Electron Microscopy with Energy Dispersive X-ray analysis (SEM/EDX) and Differential Thermal Analysis (DTA). The results of XRD show that at 1250 and 1400&deg;C the equilibrium phases are B+Pyr and probably Nd<SUB>2</SUB>O<SUB>3</SUB>-A is also present in small amount (~1%). At 1600&deg;C equilibrium phases are Flu+Nd<SUB>2</SUB>O<SUB>3</SUB>-A. Therefore, two phase transformations occur in the range 1400-1600&deg;C. DTA experiment was performed in range 25-1700&deg;C and two phase transformations have been found: Pyr &rarr;Flu at ~1471&deg;C and B&rarr;A at ~1608&deg;C. This was confirmed by XRD and SEM/EDX.}
