Electrical and Hydrogen Reduction Enhances Kinetics in Doped Zirconia and Ceria: II. Mapping Electrode Polarization and Vacancy Condensation in YSZ
Yanhao Dong, I-Wei Chen
Knowing the correlation between grain boundary mobility and oxygen potential in yttria stabilized zirconia (YSZ), we have utilized the grain size as a microstructural marker to map…
A Mathematical Treatment to Determine Transient Growth Kinetics from a Given Size Distribution
Yanhao Dong, Jian Han
Particle coarsening and grain growth take place to minimize the total interfacial energy. The classical mean-field treatments by Lifshitz, Slyozov, [1] Wagner [2] and Hillert [3] p…
Grain Growth with Size-Dependent or Statistically Distributed Mobility
Yanhao Dong, I-Wei Chen
Conventional grain growth is rate-limited by the mobility of grain boundary. To describe similar phenomena limited by the mobility of other grain junctions, we have developed a gen…
Mobility Transition at Grain Boundaries in Two-Step Sintered 8 mol% Yttria Stabilized Zirconia
Yanhao Dong, I-Wei Chen
Stagnation of grain growth is often attributed to impurity segregation. Yttria-stabilized cubic zirconia does not evidence any segregation-induced slowdown, as its grain growth obe…
On the Onset of the Flash Transition in Single Crystals of Cubic Zirconia
Yanhao Dong
The reported onset temperatures of the flash transition in cubic zirconia single crystals have been analyzed in the present note. The analysis for high-temperature low-field data g…
On the Hotspot Problem in Flash Sintering
Yanhao Dong
A perturbation analysis has been conducted to evaluate the generation of hotspots inside an electrical loaded ceramic sample, which is assumed to have an Arrhenius-type conductivit…
A Computational Study of Yttria-Stabilized Zirconia: II. Cation Diffusion
Yanhao Dong, Liang Qi, Ju Li +1
Cubic yttria-stabilized zirconia is widely used in industrial electrochemical devices. While its fast oxygen ion diffusion is well understood, why cation diffusion is much slower-i…
A Computational Study of Yttria-Stabilized Zirconia: I. Using Crystal Chemistry to Search for the Ground State on a Glassy Energy Landscape
Yanhao Dong, Liang Qi, Ju Li +1
Yttria-stabilized zirconia (YSZ), a ZrO2-Y2O3 solid solution that contains a large population of oxygen vacancies, is widely used in energy and industrial applications. Past comput…
