Redox behaviour of a ceria–zirconia inverse model catalyst [PDF]
The redox behaviour modification following the addition of zirconia to ceria nanostructures supported on Rh(111) has been investigated using a combination of Low Energy Electron Diffraction (LEED) and X-ray Photoemission Electron Microscopy (XPEEM). Soft

HARDNESS AND FRATURE TOUGHNE OF PLASMA SPRAYED ZIRCONIA-CERIA-YTTRIA THERMAL BARRIER COATINGS
Several studies have been made during the recent years to evaluate the plasma sprayed yttria partially stabilized zirconia thermal barrier coatings but less attention were undertaken on ceria-yttria stabilized zirconia.

Influence of doping of ceria and scandia on the point defects of zirconia based material
The advanced properties of rare-earth oxide doped zirconia materials are closely related to the different types of point defects which exist in zirconia crystals.These point defects are mainly in the form of oxygen vacancies.The research sample is ...

Mechanical properties of partially stabilized zirconia for dental applications
In esthetic dental care, porcelain-fused-to-metal crowns have long been used for dental restoration. Since a dental prosthesis is placed in the harsh environment of the oral cavity over long periods, metal allergy due to eluate from the metal frame has ...

Mechanical and Electrical Characterization of 8YSZ-ScCeSZ Ceramics
The effects of small amounts (up to 5 wt.%) of scandia- and ceria-stabilized zirconia on the electrical conductivity, and the elastic modulus and hardness of yttria-stabilized zirconia were investigated by impedance spectroscopy and nanoindentation tests,

Influence of roughness on initial in vitro response of cells to Al2O3/Ce-TZP nanocomposite
Al2O3/Ce-tetragonal zirconia polycrystal (TZP) nanocomposite was synthesized by a colloidal processing route and sintered in air atmosphere. Sandblasting treatment was made to alumina toughened zirconia (ATZ) nanocomposite in order to evaluate the ...
