Sol-Gel Chemistry is a process used to create materials from small molecules, typically involving the transition from a liquid solution (sol) to a solid gel. This method allows for the production of various materials, including glasses, ceramics, and thin films, by controlling the chemical reactions and conditions during the transformation. In Sol-Gel Chemistry, metal alkoxides or metal salts are often used as precursors. These compounds undergo hydrolysis and polycondensation reactions, leading to the formation of a network structure. The resulting gel can be dried and heat-treated to produce high-purity materials with specific properties, making it valuable in fields like nanotechnology and materials science.
