The Sol-Gel Process is a method used to create solid materials from small molecules. It involves transitioning a solution, or "sol," into a solid network, or "gel," through chemical reactions. This process allows for the production of various materials, including ceramics and glasses, at relatively low temperatures. During the sol-gel process, precursors undergo hydrolysis and condensation reactions, forming a three-dimensional network. This technique is widely used in fields such as materials science and nanotechnology, enabling the development of coatings, fibers, and catalysts with unique properties and structures.
