“…As early as the 1970s, oxide ceramic fibers were on the market in the form of filaments or short fibers. These fibers were mostly composed of Al 2 O 3 , [ 17 ] silicon oxide (SiO 2 ), [ 18 ] and zirconium oxide (ZrO 2 ), [ 19 ] and were usually used for high‐temperature applications due to their high melting points. Subsequently, oxide ceramic fibers evolved toward nanonization and diversification in the next 50 years for extended applications and improved performance.…”

Traditional ceramic materials are suboptimal for use in complex environments because of their brittleness and sensitivity to flaws. As such, developing flexible and elastic ceramic materials is extremely urgent in frontier domains where high-frequency vibration or high-intensity bending environments are inevitable. Fibrillation of ceramic materials is an effective way for the transition of brittleness to flexibility and elasticity, due to its ability to absorb and dissipate stresses through large axial deformations. Here, a comprehensive review of the newly emerging flexible and elastic ceramic fiber materials is presented, starting from an introduction to the fundamental concept, followed by an in-depth analysis of the relationship between their microstructures and mechanical behaviors, laying emphasis on the toughening mechanism of both individual fibers and fiber assemblies. Finally, current challenges and future development are demonstrated. It is expected that this review may provide meaningful guidance for the advancement of ceramic fiber materials toward better performance and brighter prospects.

“…(Note that, we will index phases by Greek symbols.) For this reason, an equation analogous to (2.2) holds: 4) and so similarly we need to consider only M − 1 phase variables. Therefore, at any positionx there are N different values of the compositions and M different values of the phases.…”

An enhanced understanding of the microstructure of oxide ceramics will help scientists and engineers improve their efficiency and design. A phase-field model for the composition and phase distribution of the oxide ceramic components is studied. The model, which includes an obstacle in the phase portion of the energy potential, results in a minimisation problem that characterises the distribution of the bulk phases. The transition region between them is studied in several mathematically plausible asymptotic limits. The behaviour of the system in these limits provides insights into the applicability of the model and indicates appropriate parameter regimes.

“…В настоящее время волокна Al 2 O 3 находят все более широкое применение при создании композитов и материалов с улучшенными сорбционными и каталитическими свойствами, коррозионной и износостойкостью [1,2]. Одним из эффективных методов получения дискретных волокон с развитой системой пор и высокой удельной поверхностью является «биокопирование» различных природных волокнистых материалов, в частности, целлюлозы [3][4][5][6].…”

Alumina fibres were obrained by impregnation of the cellulose biotemplate with precursor solutions in which the hydrolysis ratio [OH-]/[Al3+] is varied and in which different aluminium oligo- and polycations content. The biotemplates and alumina fibres were studied by X-ray, TG/DSC, electrophoretic light scattering, SEM, and N2 adsorption/desorption. It was shown that the infiltration with the precursor did not affect the cellulose structure. The possibility to vary the surface area, pore size and pore volume of the ceramic fibres by controlled hydrolysis of aluminum was demonstrated.
