  • Sol–gel processWikipedia

    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). The process involves conversion of monomers into a colloidal solution that acts as the precursor for an integrated network (or gel) of either discrete particles or network
