“…Applying the solegel process, it is possible to fabricate ceramic or glass materials in a wide variety of forms, including ultrafine or spherical shaped powders, thin film coatings, ceramic fibers, microporous inorganic membranes, monolithic ceramics and glasses, or extremely porous aerogel materials [46]. The solegel process is a versatile solution process to produce ceramic and glass materials [48]. In a typical solegel process, the precursor is subjected to a series of hydrolysis and condensation/polymerization reactions to form a colloidal suspension, or a "sol."…”
