Electronic structure of cubic and tetragonal zirconia

Physical Review B, 1991
The electronic structure of tetragonal zirconia with {ital D}{sub 4{ital h}}{sup 15} symmetry is investigated using density-functional theory. The Kohn-Sham equations are solved by applying the full-potential linearized augmented-plane-wave method.

Growth-controlled cubic zirconia microstructure in zirconia–titania nanolaminates

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2002
Zirconia microstructure selection (phase and crystallographic orientation) was studied in sputter-deposited multilayer films consisting of nanocrystalline ZrO2 and amorphous TiO2. The goal was to understand the mechanism for ZrO2 microstructure selection as a function of nanolaminate architecture (number of interfaces and ZrO2 and TiO2 layer thickness)

Low Temperature Stability of Cubic Zirconia

physica status solidi (a), 2000
A 9 mol% Y 2 O 3 -stabilized ZrO 2 specimen was annealed in boiling water for 1200 h, and the phase structure was examined by XRD and the chemical states of zirconium, yttrium and oxygen were examined by XPS. After annealing, the phase of the specimen remains entirely cubic, and the chemical states of the elements are not remarkably changed ...

Interface Structure of an Epitaxial Cubic Ceria Film on Cubic Zirconia

Journal of the American Ceramic Society, 2003
A cubic CeO 2 (001) film with a thickness of ∼58 nm was grown epitaxially on Y 2 O 3 ‐stablized cubic ZrO 2 by oxygen‐plasma‐assisted molecular‐beam epitaxy (OPA‐MBE).

Stabilization of cubic zirconia by carbon nanotubes

Materials Science and Engineering: A, 2004
Abstract Liquid–liquid two-phase method was used for fabricating Zirconia (ZrO 2 ) nanoparticles, sodium bis(2-ethylhexyl) sulfosuccinite (AOT) surfactant and carbon nanotubes (CNTs) were added into the solution. It has been shown that CNTs acted as the medium during the drying and burning process, which was very important to the formation of ZrO 2 ...

Modelling the Interatomic Potential of Cubic Zirconia

Applied Mechanics and Materials, 2013
Molecular modelling methods were used to investigate the structural and interatomic potential of bulk cubic zirconia. To widen the scope of the expected outcome, GULP and CASTEP software were used based on the concept of minimizing the energy of the crystal structure with respect to atomic coordinates.

Cubic zirconia as a dynamic compression window

Applied Physics Letters, 2008
Symmetric impact experiments were used to characterize the elastic response of ⟨100⟩ cubic zirconia crystals under shock wave compression. Elastic response was determined from the apparent velocity structure upon free surface release and the preservation of light passing through the compressed sample.

Stabilization of Cubic Zirconia with Manganese Oxide

Journal of the American Ceramic Society, 1994
A directionally solidified eutectic (DSE) of MnO‐ZrO 2 has been investigated using a variety of electron optical techniques. It is found that considerable MnO goes into ZrO 2 to form a substitutional solid solution. About 14 wt% of MnO is soluble in ZrO

Optical properties of cubic stabilized zirconia

Solid State Communications, 1992
Optical absorption across the fundamental edge and the associated photoluminescence, have been studied in single crystals of yttrium stabilized zirconia (YSZ) of varying yttrium concentration. The results allow discrimination of a region of intrinsic transitions (above 5.2 eV) from a low energy region, where disorder-induced transitions are dominating.
