Sol-gel is a versatile wet-chemical technique for fabricating materials – typically metal oxides – from a colloidal suspension (“sol”) into a solid-like gel. This process involves controlled hydrolysis and condensation reactions of precursors, often metal alkoxides or inorganic salts, allowing for the creation of diverse materials with tailored microstructures and compositions. Its importance stems from its low processing temperatures, enabling synthesis of materials inaccessible via traditional high-temperature methods, and its ability to produce high-purity, homogeneous products. Applications span numerous fields including ceramics, coatings, catalysts, biomedical materials, and optics, driving significant research in areas like nanotechnology, thin film deposition, and advanced materials science. Related concepts include hydrolysis, condensation, xerogels, aerogels, and sol-gel coatings, all contributing to the broad applicability of this methodology.
