1 Sol-Gel methods The sol-gel process may be described as: ”Formation of an oxide network through polycondensation reactions of a molecular precursor in a liquid.”
Sol-gel processing is a wet chemical route to synthesis of a colloidal suspension of solid particles or clusters in a liquid (sol) and subsequently to formation of a dual phase material of a solid skeleton filled with a solvent (wet gel) through sol-gel transition (gelation).
