Electronic Structure and Dielectric Properties of Cubic Zirconia

Japanese Journal of Applied Physics, 2003
The electronic structure and dielectric properties of cubic zirconia (ZrO2) are investigated by the linear muffin-tin orbital method. The band structure and density of states of ZrO2 are calculated by the local density approximation and GW approximation.

Intrinsic vacancies in cubic-zirconia bulk and surface

Journal of Alloys and Compounds, 2010
Abstract Formation of charged (neutral) vacancies of bulk (surface) cubic-ZrO 2 is calculated from density functional theory, and compared with available experiments. Relationships among vacancy formation energy, electron and element chemical potentials are established within a wide range of oxygen chemical potentials. The +2 (−2) oxygen (zirconium)

Diffuse scattering in yttria-stabilized cubic zirconia

Journal of Solid State Chemistry, 1992
Abstract We have used a position-sensitive detector (PSD) system to make measurements of the diffuse X-ray scattering on a cubic Y 2 O 3 -stabilized zirconia, Zr 0.61 Y 0.39 O 1.805 , in far greater detail than has hitherto been reported. In addition to the fairly prominent diffuse peaks visible in 〈1 1 0〉 sections that have been the center of ...

Solubility of Mn stabilized cubic zirconia nanostructures

Journal of Materials Science: Materials in Electronics, 2013
Mn-stabilized cubic zirconia nanostructures (Zr1−xMnxO2, x = 0.10, x = 0.15 and x = 0.20) have been prepared using chemical precipitation method for different doping concentrations. The prepared powders have been characterized by X-ray diffractometer for structural analysis, vibrating sample magnetometer for analyzing magnetic properties, scanning ...

Research on crystal growth and defects in cubic zirconia

Journal of Crystal Growth, 1986
Abstract The crystal growth and defects in cubic zirconia grown by the skull melting method have been investigated. The distribution coefficients of stabilizers Y 2 O 3 and CaO in the crystal were greater than 1 and less than 1 respectively.

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 ...

Absorption Spectrum of Er3 + Ions in Cubic Zirconia

Physica Status Solidi (a), 1972
Yttria-stabilized zirconia crystals doped with Er3+ ions were prepared from the melt using a large solar furnace. In order to investigate the oxygen ion coordination around Y3+ ion using Er3+ ion as a probe, the absorption spectra of the crystals were measured in the spectral region 30000 to 4000 cm−1.

Verification of Existence of Cubic Zirconia at High Temperature

Journal of the American Ceramic Society, 1962
The existence of the high-temperature cubic form of ZrO/sub 2/ was verified with an x-ray diffractometer. The 200 and 002 doublet was taken as the best indicator of the phase change, and the tnansformation was found to occur at 2285 plus or minus 15 deg C with first order kinetics.

Orbital-decomposed electronic structures of cubic zirconia

Solid State Communications, 2012
The detailed orbital-decomposed electronic structures of the cubic zirconia have been investigated by using the first-principles projector augmented wave (PAW) potential within the generalized gradient approximation (GGA) as well as taking into account the on-site Coulomb repulsive interaction (GGA þU). The optimized lattice constant of 5.086 ˚ A is in
