sol-gel technology

Sol-gel technology is a process of creating solid materials from liquids. It begins with a solution called a "sol"—a mixture of tiny, reactive particles. Over time, the sol transforms into a gel, a semi-solid network of interconnected particles. Through controlled drying and heating, this gel turns into a dense, durable material like glass or ceramics. This method allows precise control over the material’s composition and properties, making it useful for producing advanced coatings, fibers, and biomedical devices with tailored functionalities.
