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 and titanium.

What are the steps involved in sol gel process?

The sol–gel process is a wet chemical technique also known as chemical solution deposition, and involves several steps, in the following chronological order: hydrolysis and polycondensation, gelation, aging, drying, densification, and crystallization.

What is mean by sol gel method?

Sol--gel method

Definition: The process of the settling of (nm sized) particles from a colloidal suspension onto a pre-existing surface, resulting in ceramic materials.
