Sol–gel process - Wikipedia

The Stöber process is a well-studied example of polymerization of an alkoxide, specifically TEOS.The chemical formula for TEOS is given by Si(OC 2 H 5) 4, or Si(OR) 4, where the alkyl group R = C 2 H 5. Alkoxides are ideal chemical precursors for sol–gel synthesis because they react readily with water. The reaction is called hydrolysis, because a hydroxyl ion becomes attached to the silicon ...
