Abstract
Structural development was systematically studied in Zr1-xMnxO2-δ(x = 0~0.5) prepared at the sintering temperature of 1400℃ in Ar for 12h. It is found that the Mn ions go into the crystal lattice of ZrO2 to form a solid solution without any other compounds formed. After post treatment in high oxygen partial pressure, the cubic phase transforms into the monoclinic phase. We believe that the high symmetry phase can be retained to room temperature due to the effects of vacancy compensation and lattice distortion..
