抄録

The chemical bonding states of silica-doped YTZP are computed by the DV-Xα molecular orbital calculation. It is clarified that silicon ions substituted into the lattice of TZP have extremely high covalent bonding with oxygen ions, while other cations, magnesium and titanium ions reduce the covalency. The increment of covalency of bondings around doped cations seems to have a critical role to exhibit thee improved tensile ductility in silica-doped YTZP.
