Electrode and Electrolyte Materials From Atomistic Simulations: Properties of LixFEPO4 Electrode and Zircon-Based Ionic Conductors

Frontiers in Energy Research, 2021
LixFePO4 orthophosphates and fluorite- and pyrochlore-type zirconate materials are widely considered as functional compounds in energy storage devices, either as electrode or solid state electrolyte.

Microstructure and Phase Composition of Yttria-Stabilized Zirconia Nanofibers Prepared by High-Temperature Calcination of Electrospun Zirconium Acetylacetonate/Yttrium Nitrate/Polyacrylonitrile Fibers

Fibers, 2019
For the first time, dense nanofibers of yttria-stabilized tetragonal zirconia with diameter of ca. 140 nm were prepared by calcination of electrospun zirconium acetylacetonate/yttrium nitrate/polyacrylonitrile fibers at 1100−1300 °C.

Optical properties of translucent zirconia: A review of the literature

The EuroBiotech Journal, 2019
Translucent monolithic zirconia is the newest option of zirconia-based ceramics, which aimed to substitute the opaque classic yttria-stabilized tetragonal zirconia polycrystal (Y-TZPs) in more demanding esthetic cases.

Effect of Bismuth Oxide on the Microstructure and Electrical Conductivity of Yttria Stabilized Zirconia

Sensors, 2016
Bismuth oxide (Bi2O3)-doped yttria-stabilized zirconia (YSZ) were prepared via the solid state reaction method. X-ray diffraction and electron diffraction spectroscopy results indicate that doping with 2 mol% Bi2O3 and adding 10 mol% yttria result in a ...

Electrocatalytic Enhancement of CO Methanation at the Metal–Electrolyte Interface Studied Using In Situ X-ray Photoelectron Spectroscopy

C, 2023
For the direct reduction of CO2 and H2O in solid oxide electrolysis cells (SOECs) with cermet electrodes toward methane, a fundamental understanding of the role of elemental carbon as a key intermediate within the reaction pathway is of eminent interest.

Contact damage in an yttria stabilized zirconia: Implications

Journal of Materials Science: Materials in Medicine, 2007
This paper presents the results of a combined experimental and computational study of contact damage in a 3 mole% yttria partially stabilized zirconia (3-YSZ) that is relevant to hip implants and dental restorations. Contact-induced loading in real applications is idealized using Hertzian contact model to explain plasticity phenomena and failure ...

Cytotoxicity and biocompatibility of high mol% yttria containing zirconia [PDF]

Restorative Dentistry & Endodontics, 2020
ObjectivesYttria-stabilized tetragonal phase zirconia has been used as a dental restorative material for over a decade. While it is still the strongest and toughest ceramic, its translucency remains as a significant drawback.

High Temperature Stability of Yttria Stabilized Zirconia

Netsu Bussei, 2007
イットリア安定化ジルコニアは熱物性に関する標準物質候補材料として研究が進められている。本研究では、ファインセラミックス共通試料であるリファセラムZR1（ジルコニア）を用い、標準物質材料として使用する際に重要となる高温安定性の評価を行った。高温安定性は、200～ 1500℃の温度で熱処理を行ったときの、熱処理前後の熱拡散率の変化より評価した。900℃以下の熱処理では熱拡散率に変化がほとんど見られなかったが、1000℃以上で熱処理すると、結晶相の変化や相分離および粒界に発生した亀裂などによって熱拡散率に変化が生じることが明らかになった。これらの結果より、リファセラムZR1 は900℃以下であれば安定であり、標準物質として適用できると判断された。
