Adsorption of Water on Yttria-Stabilized Zirconia [PDF]

The Journal of Physical Chemistry C, 2015
Water adsorption on the cubic (111) surface of yttria-stabilized zirconia (YSZ) was investigated using density functional theory calculations. Relaxation of atomic positions away from ideal cubic lattice sites, in particular of the oxygen anion sublattice, is observed on including both phase-stabilizing dopants and water adsorption.

Interaction of zirconia primers with yttria-stabilized zirconia surfaces

Dental Materials, 2016
Recently several zirconia primers have been introduced to mediate bonding of dimethacrylate resins to yttria-stabilized zirconia frameworks (Y-TZP). The aim of the study was to evaluate the changes in surface chemistry of Y-TZP frameworks induced by zirconia primer treatments.Polished Y-TZP discs (Lava, 3M ESPE), ultrasonicated for 10min in ethanol ...
