EXAFS Studies of Yttria Stabilized Zirconia
1984Yttria stabilized zirconia is a well known solid electrolyte which exhibits fast anion conduction at elevated temperatures. Below 1200° C pure zirconia (ZrO2) is monoclinic, but forms a stabilized cubic phase with the fluorite structure in a solid solution with 9.4 to 24 mole percent Y2O3.

On the conduction pathway for protons in nanocrystalline yttria-stabilized zirconia
Physical Chemistry Chemical Physics, 2009In this communication we elucidate a microstructural picture of proton conduction in nano-crystalline yttria-stabilized zirconia at low temperatures (Kim et al. Adv. Mater., 2008, 20, 556). Based on careful analysis of electrical impedance spectra obtained from samples with grain sizes of approximately 13 and approximately 100 nm under both wet and dry

Raman Investigation of the Nitridation of Yttria‐Stabilized Tetragonal Zirconia
Journal of the American Ceramic Society, 2003Raman spectroscopy has been used to obtain Raman spectra of yttria‐stabilized tetragonal zirconia subject to surface nitridation induced by contact with zirconium nitride. Raman spectra recorded from regions at increasing distance from the source of nitridation have been used to obtain diffusion profiles from samples treated at ...

Interaction of NiO with yttria-stabilized zirconia
Solid State Ionics, 1997Abstract As-prepared and heat treated plasma-produced 8 and 10 mol% yttria-stabilized zirconia (YSZ) powders doped with 0, 5, 10 and 75 mol% NiO have been investigated by XRD. The as-prepared powders are mixtures of metastable tetragonal and cubic phases but they transform to a single YSZ phase upon heat treatment above 1200 °C. The solubility of NiO

In Vitro Aging of Yttria‐Stabilized Zirconia
Journal of the American Ceramic Society, 1989Yttria‐stabilized zirconia was aged in distilled water, saline, and Ringer's solution for 140, 304, and 453 d. The significant decreases in strength (13% to 22%) is attributed to the phase transformation of zirconia from tetragonal to monoclinic. The effect of aging stabilized zirconia in physiological media is still unresolved.

Yttria-stabilized Zirconia with beige colour
2018Zirconia is a very versatile advanced ceramic that offers an interesting combination of thermal, chemical, electrical, mechanical and optical properties which are uncommon to find in ceramic materials and therefore is used in several applications. INNOVNANO is one of the main Zirconia powders suppliers in the market with potential clients for beige YSZ
