Subsurface segregation of yttria in yttria stabilized zirconia

Journal of Applied Physics, 2002
The segregation behavior in 3 and 10 mol % polycrystalline yttria stabilized zirconia (YSZ), calcined at temperatures ranging from 300 to 1600 °C, is characterized using low-energy ion scattering (LEIS). In order to be able to separate the Y and Zr LEIS signals, YSZ samples have been prepared using isotopically enriched Z94rO0 instead of natural ...

Synthesis of yttria nanopowders for transparent yttria ceramics

Optical Materials, 2006
Abstract This paper describes a precipitation process for synthesizing nanocrystalline yttria powder and sintering transparent yttria ceramics. Hydroxide precursor of Y 2 O 3 with an approximate composition of Y 2 (OH) 5 NO 3  · H 2 O was synthesized by using ammonia water as precipitant and yttrium nitrate as the starting salt.

Mechanical Strength of Hemispheric Domes of Yttria and Lanthana‐Doped Yttria

Journal of the American Ceramic Society, 1992
The strength of hemispheric ceramic domes was measured in a biaxial flexure test using disklike circular pieces removed with a core drill. Yttria and lanthana‐doped yttria dome cores exhibit approximately 60% of the strength predicted from similarly fabricated flat disks.

Hydrothermal Synthesis of Yttria-Stabilized Zirconia Nanocrystals with Controlled Yttria Content

Inorganic Chemistry, 2015
In this study, we demonstrate for the first time the hydrothermal synthesis of yttria-stabilized zirconia (YSZ) nanocrystals with controlled yttria content (x = 3-12 mol %; xYSZ) with negligible aggregation from aqueous solution. The nanocrystals were grown via the hydrothermal treatment of basic Zr(IV) and Y(III) carbonate complex aqueous solutions in
