Electric field driven solid state reactions—reaction kinetics and the influence of grain boundaries on the interface morphology in the system MgO/MgIn₂O₄/In₂O₃

Orientation Relationships of SrTiO3and MgTiO3Thin Films Grown by Vapor−Solid Reactions on (100) and (110) TiO2(Rutile) Single Crystals

“…In such model experiments, the formation and orientation of the reaction products can be well-characterized by several structural techniques such as X-ray diffractometry and transmission electron microscopy (TEM). This approach has been used successfully by several research groups to study interfacial reaction mechanisms and reaction kinetics in oxides. − …”

“…This approach has been used successfully by several research groups to study interfacial reaction mechanisms and reaction kinetics in oxides. [4][5][6][7][8][9][10] Recently, we investigated the formation of BaTiO 3 in model experiments on (110) and (100) TiO 2 (rutile) single crystals. 11,12 We found more than one orientation relationship for BaTiO 3 (which is cubic at temperatures higher than 120 °C, a ≈ 0.4 nm, but tetragonal at room temperature) grown on the rutile substrates, depending on the reaction temperature.…”

Impurity Segregation and Nanoparticle Reorganization of Indium Doped MgO Cubes

“…where the associated kinetics and morphological aspects were investigated by Korte et al [11] Corresponding findings underline the determining role of grain boundaries as fast diffusion paths sustaining the solid-state reaction. In order to fully realize the range of device applications where metal oxide nanocomposites serve as precursor structures, it is necessary to understand compositional, structural and topographical changes inside the intergranular regions that occur during nanoparticle processing spanning the range from particle synthesis to sintering.…”

Electric Field‐Induced Microstructural Evolution in Polycrystalline Bi2O3‐Doped ZnO in Presence of a Secondary Liquid Phase

“…Furthermore, electric fields presented in solid oxide fuel cells [6,7] and other electrochemical or electronic devices can cause microstructural instability and degradation, which can often be accelerated with increasing temperature. It has been reported that applied electric fields and currents can affect the phase stability [8] and grain growth, [9][10][11][12][13][14][15][16][17] enhance phase transformation kinetics [18][19][20] and sintering, [21,22] and cause failures (e.g., via cracking and dielectric breakdown). [23] Specifically, electric fields can influence microstructural evolution to produce a spectrum of interesting phenomena with elusive underlying mechanisms.…”
