Effect of Co-Doping Cation on Phase Stability of Zirconia Bioceramics in Hot Water

Abstract:

Article Preview

Phase stability of cation co-doped zirconia ceramics is examined. As the result, in contrast to the result in small amount of single cation doped zirconia, phase stability of co-doped zirconia ceramics can not be simply explained from ionic radius and valency of dopant or from the change in axis ratio. We focus on oxygen vacancy concentration and binding energy between oxygen vacancy and doped cation. By estimating phase stability from these factors, it is found that concentration of oxygen vacancy and the binding energy between the dopant and the oxygen vacancy are important factors for understanding the phase stability of zirconia ceramics.
