A sol gel process is based on

Step-by-step solution

The sol-gel process is a method for producing solid materials from small molecules. The process involves the conversion of monomers into a colloidal solution (sol) that acts as the precursor for an integrated network (or gel) of either discrete particles or network polymers. Typical precursors are metal alkoxides and metal chlorides, which undergo hydrolysis and polycondensation reactions. These reactions are essentially inorganic polymerization reactions, leading to the formation of a continuous inorganic network.
