Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" (Zr O 2) and "yttria" (Y 2 O 3), hence the name.

Jun 15, 2022 · Numerous studies have shown that doping rare earth oxides (RE 2 O 3) with different atomic masses or radii into YSZ systems is an effective method for improving thermal insulation performance...

Apr 1, 2024 · The yttria-stabilized zirconia (YSZ) coatings were doped with various concentrations of Yb 2 O 3 to build a multi-component solid solution system.

Nov 1, 2024 · Yb₂O₃ doping significantly reduces the infrared emissivity of YSZ, with 3 mol% identified as optimal. Due to its exceptional thermal stability and high conductivity, Yttrium stabilized zirconia (YSZ) has become an essential material in the field of infrared camouflage.

Jan 14, 2022 · In this paper, YSZ doped tungsten alloy materials with uniform distribution, high relative density and excellent properties were prepared by combining the advantages of liquid phase method and second phase doping.

Aug 25, 2018 · Yttria-stabilized zirconia (YSZ) is a very well-known oxide ion conductor that is used as the solid electrolyte in solid oxide fuel cells and oxygen gas sensors. 1 – 3 It usually takes the form of a high-density ceramic in which the bulk resistance in series with a grain boundary resistance gives the overall sample resistance. 4 In almost all ...

Sep 7, 2021 · Chemical effect of rare earth element erbium (Er) doped in yttria-stabilized zirconia (YSZ) is studied via experimental and theoretical methods in calcium-magnesium-alumino-silicate (CMAS) melt.

Yttria-stabilized zirconia (YSZ) is a widely recognized ceramic of distinct elec- trical, mechanical and optical properties. Although YSZ is an intrinsically para- magnetic solid, it could potentially transform to a magnetic semiconductor by incorporating in its crystalline structure isolated atoms bearing unpaired valence electrons.

This study investigates rare earth doped YSZ (ZrO2: 2mol% Y2O3 + 1mol% Yb2O3 + 1mol% Gd2O3) and the rare earth pyrochlore Gd2Zr2O7 as possible replacements for 7YSZ.

Apr 13, 2020 · Samples of 8 mol% Y 2 O 3 -stabilized ZrO 2 (8YSZ) doped with Fe were prepared and sintered at 1350°C in air or argon atmosphere. The sintered samples were characterized by SEM, XRD, and Raman spectroscopy.
