In materials science, the sol–gel process is a method for producing solid materials from small molecules. The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). ... Typical precursors are metal alkoxides.

What is sol gel used for?

Sol gel technology can be used to prepare fibers, microspheres, thin films, fine powders and monoliths. Applications for sol gel technology include protective coatings, catalysts, piezoelectric devices, wave-guides, lenses, high-strength ceramics, superconductors, synthesis of nanoparticles and insulating materials.

What is meant by sol gel?

Sol–gel is a wet-chemical process that involves the formation of an inorganic colloidal suspension (sol) and gelation of the sol in a continuous liquid phase (gel) to form a three-dimensional network structure. From: Corrosion Protection and Control Using Nanomaterials, 2012.
