Product Description
Product Description
Tetraethylorthosilicate (TEOS), also known as tetraethoxysilane, is a chemical compound with the formula Si(OC2H5)4. It is an inorganic compound that belongs to the organosilicon family. TEOS is a colorless liquid that has a distinct odor.
TEOS is primarily used as a precursor in the production of silica-based materials. It is commonly employed in the synthesis of silicon dioxide (SiO2) or silica sol-gels, which have various applications in industries such as electronics, optics, coatings, and ceramics.
In the production of silica sol-gels, TEOS undergoes hydrolysis and condensation reactions. When TEOS reacts with water, it forms silanols (Si-OH) and ethanol. The silanols can further react with each other to form siloxane bonds (Si-O-Si), leading to the formation of a three-dimensional network of silica particles.
TEOS is also used in the manufacturing of optical fibers, where it serves as a precursor for the deposition of a silica-based layer on the fiber core. This layer helps to protect the fiber and maintain its transmission properties.
Additionally, TEOS finds applications as a cross-linking agent in the production of silicone polymers and as a coating material for surfaces to enhance their hardness, durability, and resistance to moisture and chemicals.
It is important to note that TEOS is a highly reactive substance and should be handled with care. It can cause severe irritation to the skin, eyes, and respiratory system. Proper safety precautions and handling procedures should be followed when working with TEOS to ensure personal safety and prevent environmental hazards.
