DSC (differential scanning calorimeter) measurements were performed to investigate the tetragonal-monoclinic (t-m) transition enthalpy of the compositionally homogeneous ZrO{sub 2}-X mol% CeO{sub 2} solid solution of X = 0, 4, 8, and 12. The transition enthalpy decrease linearly with an increase of CeO{sub 2} content. The m {yields} t transition enthalpy on heating agreed well with the inverse t {yields} m one obtained during cooling. with increasing X, the DSC peak broadens and the transition temperature distribution of each sample increases, while the thermal hysteresis is almost independent of X.
