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.

2021年12月24日 · Today, various methods such as sol-gel method (solution method), vapor phase compression method, mechanical alloying method or collision with high-energy pellets, plasma method, and electrochemical methods are used …

2023年1月28日 · Sol gel methods are based on the principle of transition of materials from the solution or sol phase to the gelatinous or gel phase. It is a process of oxide network formation via polycondensation reaction in the solution phase.

The sol-gel method is a traditional method used for a wide range of materials, including inorganic membranes, monolithic glasses and ceramics, thin films, and ultra-fine powders. Today, it is even used to synthesize 1D nanomaterials.

2020年10月28日 · Sol-gel method is a method, for material preparation under mild condition, of solidifying a compound containing a highly chemically active component through a solution, sol, or gel, and then...

The sol-gel method is a wet chemical process of making oxide-based materials starting from hydrolyzable precursors via hydrolysis and condensation. The precursors usually contain weaker ligands as compared to water such as halides, nitrates, sulfates, alkoxides, or carboxylates.

2020年2月11日 · The sol-gel process is a chemical route that transforms solvated molecules or ions into solid-state materials. Although established from earlier works in the mid-nineteenth century, the basics and applications of the sol-gel process have emerged in the 1950s and have become part of the material scientists’ toolbox for more than 30 years.

The sol-gel process is a method for preparing new materials that allows for better control of the reactions involved in synthesizing solids. It is based on hydrolysis and polycondensation reactions, utilizing metal alcoxides as versatile molecular precursors to obtain oxides.

Using sol-gel methods, protective coatings can be made at modest (less than 150°C) temperatures. These coatings can be tailored for specific applications including: mechanical protection for soft substrates (such as plastics and metals), chemical protection for reactive substrates, and environmental protection for exposed surfaces.
