Scalable preparation of hollow ZrO2 microspheres through a liquid-liquid phase reunion assisted sol-gel method

High photocatalytic activity of aerogel tetragonal and monoclinic ZrO2 samples

“…The choice of the preparation method is therefore an important parameter that can influence the properties and performance of any catalyst. Different synthesis methods such as solvothermal [44], co-precipitation [45], hydrothermal [46], microwave-assisted synthesis [47], chemical vapour synthesis [48] and sol-gel [49] have been used to synthesize ZrO2 nanostructures. However, large surface areas obtained in materials synthesized by sol-gel methods allow the preparation of pure and mixed oxides with desirable properties.…”

ZrO2 Matrix Toughened Ceramic Material‐Strength and Toughness

“…Besides, ZrO 2 is also commonly used in thermal barrier ceramic coatings due to its good thermal shock resistance, chemical stability, and thermal insulation performance. [ 5–7 ] Song et al [ 8 ] prepared Yb 2 O 3 –Gd 2 O 3 –Y 2 O 3 co‐doped ZrO 2 (YGYZ) coating by plasma spraying. After the hot corrosion test, the YGYZ coating exhibited the maintenance of tetragonality ratio and low extent of degradation, which shows great chemical and phase stability.…”

Synthesis of tubular silica fiber via all‐aqueous microfluidics for geopolymer regulation

“…The commonly used methods to synthesize preceramic templates include sol-gel, [14][15][16][17] gel casting, 18,19 replica, [20][21][22] 3D printing, [23][24][25][26] microfluidics, 27,28 and so forth. Liang et al 29 introduced a phase reunion assisted sol-gel method to prepare hollow ZrO 2 microparticles, which improved the efficiency by reducing the equilibrium time needed for the sol-gel system. However, the droplets derived from the mechanical stirring showed obvious dimensional inhomogeneity, and the transition of the system to reach balance still took a certain time.…”
