The sol–gel process is a wet-chemical technique used for the fabrication of both glassy and ceramic materials. In this process, the sol (or solution) evolves gradually towards the formation of a gel-like network containing both a liquid phase and a solid phase.

2023年12月1日 · Sol-gel derived additive manufacturing appears an important field of application for fabricating bio and active glasses with a high degree of purity in complex shapes to be used, for instance, as bio-scaffolds for tissue regeneration.

2022年1月1日 · The ceramic sol–gel coating increased the corrosion resistance and thermal properties of the coated materials while remaining a low-cost approach. This paper highlights current reports on the various applications of sol–gel ceramic coatings.

2023年8月30日 · The sol-gel process allows synthesizing ceramic materials of high purity and homogeneity by a process that occurs in a liquid solution of organometallic precursors (TMOS, TEOS, Zr (IV)—Propoxide, Ti(IV)—Butoxide, etc.), which, by means of hydrolysis and condensation reactions, lead to the formation of a new phase (SOL).

Ceramic sol-gel coatings are hard, dense and well adhered to metal substrates when manufacturing parameters are optimized, but fracture toughness of the layer, essential property for wear performance, is usually low.

2022年5月1日 · Sol-Gel, (otherwise known as Ceramic) materials are formed from small inorganic particles suspended in solution that gel together to form an inorganic matrix. Sol-Gel technology was first introduced around 20 years ago, these non-stick ceramic coatings come in several proprietary blends, and can vary slightly, but they’re all inorganic.

Sol-gel processing is beneficial in the formation of ceramic and glass films for many reasons. It is a simple reaction that does not require exotic materials, catalysts or expensive deposition equipment.

2021年4月22日 · Sol–gel-derived ceramics, glasses, and composites offer distinct properties that can be taken advantage of in order to shape or fashion materials with uses ranging from thin films to matrixes, fibers, and monoliths, amongst others .

We present an overview of the ceramic-based nanofiber obtained by sol–gel routes for high-performance thermal management, including the materials, the fabrication methods of the sol–gel route, and their application for thermal management.

Major technologies that use the solution-sol-gel route have been developed to make nuclear fuel pellets, ceramic fibers, thin coatings, and abrasive grain. This article reviews the early history and summarizes present research in this field, particularly new processes aimed at achieving xerogel precursors of maximum heterogeneity with respect ...
