Microstructural development, electrical properties and oxygen permeation of zirconia-palladium composites [PDF]
, 1995 Yttria-stabilized cubic zirconia (YSZ)-palladium dual phase composites have been investigated. The percolative composite containing 40 vol% Pd (ZYPd40) showed a much larger oxygen permeability than that of the non-percolative composite containing 30 vol%

Catalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application [PDF]
, 2009 Catalyst layers (4–20 lm) of rhodium (1 wt%) supported on alumina, titania, and ceria–zirconia (Ce0.5Zr0.5O2) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water.

Journal of Advanced Materials in Engineering, 2010 The addition of ZrO2 particles to the HA coating has received considerable attention because ZrO2 particles increase the bonding strength between HA coating and substrate. In this study, nanostructured hydroxyapatite (HA)/yttria stabilized zirconia (YSZ)

The brittle/ductile transition in cubic stabilised zirconia
Journal of the European Ceramic Society, 1994 Abstract Cubic zirconia has a smooth brittle/ductile transition above 800°C at a loading rate of 1·2 × 10 −4 MPa m s −1 . Pre-stressing at 950°C increases the room temperature fracture toughness in a controllable manner. The toughness increase is caused by dislocation shielding of the crack tip and may be predicted using a model ...

Growth Stress Induced Tunability of Dielectric Constant in Thin Films
, 2015 It is demonstrated here that growth stress has a substantial effect on the dielectric constant of zirconia thin films. The correct combination of parameters - phase, texture and stress - is shown to yield films with high dielectric constant and best ...
