Tetraethyl Orthosilicate (TEOS), identified by the CAS number 78-10-4, is a fascinating and highly versatile organosilicon compound that plays a crucial role across numerous industrial sectors. As a leading manufacturer and supplier, we understand the importance of this chemical intermediate and are committed to providing high-quality TEOS to meet diverse application demands. If you are in the market to buy TEOS, understanding its core chemical properties and widespread uses is essential.
Chemically, TEOS is the ethyl ester of orthosilicic acid, with the molecular formula Si(OC2H5)4. It presents as a colorless liquid with a characteristic sharp, alcohol-like odor. Its key chemical characteristic is its reactivity with water, a process known as hydrolysis. In the presence of acidic or basic catalysts, TEOS readily hydrolyzes to form silanol groups (Si-OH), which then undergo condensation to create siloxane (Si-O-Si) bonds. This fundamental reaction is the basis for the sol-gel process, enabling the formation of silica networks.
The solubility of TEOS in common organic solvents like ethanol and 2-propanol, while being practically insoluble in water, makes it convenient for various solution-based industrial processes. Its ability to act as a precursor for silicon dioxide (SiO2) is perhaps its most significant application. This makes it invaluable for creating advanced materials such as thin films, protective coatings, and high-performance ceramics. Furthermore, TEOS serves as an effective crosslinking agent in silicone polymers, enhancing their mechanical strength and durability.
The applications stemming from these properties are extensive. In the electronics industry, TEOS is vital for depositing SiO2 thin films in semiconductor manufacturing. It is also used in the production of optical glass, as a binder in precision casting, and for surface modification to impart hydrophobicity or chemical resistance. For businesses looking to procure this essential chemical, our position as a reputable manufacturer and supplier in China allows us to offer competitive pricing and a reliable source for your procurement needs. Discover the potential of TEOS for your innovations.
