Yttria magnesia co-stabilized zirconia refractories for application as functional components in continuous steel casting

open access: yesOpen Ceramics, 2023
Zirconia is one of the most promising functional refractory materials in continuous steel casting and is employed in areas with high thermal and chemical stresses such as the slag line, the nose of monoblock stoppers or the inlet area of submerged entry ...

Oxygen transfer properties of ion-implanted yttria-stabilized zirconia [PDF]

open access: yesSolid State Ionics, 1992
The influence of surface modification by ion implantation on oxygen transfer in yttria-stabilized zirconia (YSZ) has been studied. Implantation of 15 keV 56Fe in YSZ with a maximum dose of 8×1016 atoms cm−2 yields reproducible surface layers of approximately 20 nm deep with a maximum Fe cation fraction of 0.5 at the surface.

Superelastic High‐Entropy Oxide Ceramic Aerogels for Thermal Superinsulation and Sealing at Extreme Conditions

open access: yesAdvanced Science, EarlyView.
A high‐entropy oxide ceramic of (Gd1/2Lu1/2)2(Ti1/3Zr1/3Hf1/3)2O7 is prepared through a molecular synthesis route of pyrolytic solid‐solution reactions. The architectured nanofiber aerogel manifests unprecedented thermomechanical properties, including superelastic compressibility of 98% from −196 to 1500 °C, and thermal superinsulation capacity (24.14 ...

High‐Efficiency CO2 Electrolysis Enabled by Interface‐Engineered Composite Electrolytes in Ni‐Based SOEC

open access: yesAdvanced Science, EarlyView.
This study addresses the critical issue of delamination between YSZ and GDC electrolytes in SOECs, which is caused by Thermal deformation disparity. A novel YSZ‐GDC composite interlayer, fabricated using a simple dip‐coating method, is introduced to solve this problem. This layer effectively suppresses delamination by mitigating thermal stress.

High temperature deformability of ductile flash-sintered ceramics via in-situ compression

open access: yesNature Communications, 2018
Flash sintering allows for rapid ceramic processing, but the mechanical behavior of such ceramics remains poorly understood. Here, the authors compress micropillars of yttria stabilized zirconia to show flash sintering promotes outstanding plasticity.

Cathode Processing Optimization Toward Solid‐State Batteries with Monolithic Oxysulfide Glassy Solid Electrolytes

open access: yesBatteries &Supercaps, EarlyView.
Mixing order and mixing time affect the ionic and electronic transport properties through a composite cathode made from lithium iron pyrophosphate, an oxysulfide glassy solid electrolyte, and conductive carbon. It is proposed that optimized milling conditions help create robust conduction networks in the composite. Seeking to further the development of

Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

open access: yesCarbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.
