Biaxial strength of YSZ gradually improves by decreasing yttria content, in the region 8–3.5 mol.%. Below this value, a significant increase to ~2 GPa is first showed for …
The yttria amounts in zirconia have been increased to improve optical properties, which are also attributed to the increase in the cubic phase.2,6,7,20,21 The increase in cubic phase from 3Y-TZP to 4Y-PSZ is 20% and 31% to 5Y-PSZ, accompanied by a 2.1% increase of yttria from 3Y-TZP to 4Y-PSZ and 4.3% from 3Y-TZP to 5Y-PSZ …
Pure zirconia will transform into different phases, which include monoclinic, tetragonal, and cubic, at different high temperature levels. Specific phases can be retained at room temperature by adding stabilizer and yttria is one of the most common …

Yttria is an excellent trivalent-ion host material for solid-state lasers. A variety of candidate metal-ion dopants and many other rare earth metals have been investigated. Yttria has a band gap of approximately 6.0 eV. This chapter provides an overview of the measurements performed on the optical constants of yttria.
The materials studied in this work were yttria-stabilized zirconia (YSZ) ceramics sintered from commercial starting powders. The zirconia and yttria powders were produced at the Vol'nogorskii Mining and Smelting Plant, Vol'nogorsk, Ukraine. Particle sizes were in the range of 100–150 nm for ZrO 2 and 10–30 nm for Y 2 O 3 powder.

Yttria stabilized tetragonal zirconia polycrystals were prepared using mixtures of two different powders. One is composed of nanometric particles of 3.5 mol% Y2O3 solid solution in ZrO2 and the ...
Yttria coatings 0.5–1.5 μm thick were deposited by electron-beam physical vapor deposition (EB-PVD) (CS400ES, Von Ardenne, Dresden, Germany) using cold-pressed yttria targets (Grade C > 99.95% ...
The present investigation deals with the development of AA-7075 metal matrix composites reinforced with nano yttria particles (0.1 to 3 vol.%) and micron yttria particles (1 to 15 vol.%) by powder forging. Matrix powders (AA-7075) and reinforcement powders (yttria) were blended, cold compacted, sintered under pure nitrogen, and finally hot …
