The processing of TEOS in nanotechnology typically involves its hydrolysis and condensation. Here are the general steps:
1. Hydrolysis: TEOS reacts with water in the presence of an acid or base catalyst. This reaction produces ethanol and silicic acid intermediates.
2. Condensation: The silicic acid intermediates undergo condensation reactions to form SiO2. This can result in the formation of a gel or solid silica particles, depending on the conditions.
3. Aging and Drying: The gel formed from the sol-gel process can be aged to improve its properties and then dried to remove any remaining solvents.
