Tetraethyl Orthosilicate, widely known as TEOS (CAS 78-10-4), is a versatile chemical compound with a significant role in various industrial and research applications. Understanding its properties, handling requirements, and sourcing is key for any professional working with this material. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive information and a reliable supply of high-purity TEOS from our base in China.

TEOS is a colorless liquid with a sharp, alcohol-like odor. Its chemical formula, Si(OC2H5)4, indicates it is the ethyl ester of orthosilicic acid. Key physical properties include a boiling point of approximately 168-169°C and a density around 0.933 g/mL at 20°C. A crucial aspect of TEOS chemistry is its reactivity with water, undergoing hydrolysis to form silicon dioxide (SiO2) and ethanol. This characteristic is fundamental to its use in sol-gel processes and thin-film deposition.

From a safety perspective, TEOS is classified as a flammable liquid and vapor, requiring careful handling and storage away from ignition sources. It can cause serious eye irritation and may cause respiratory irritation if inhaled. Therefore, it is essential for users to consult the Safety Data Sheet (SDS) and employ appropriate personal protective equipment (PPE), such as gloves, safety glasses, and adequate ventilation, when working with TEOS. Understanding these safety protocols is vital for any buyer looking to purchase TEOS.

The primary applications of TEOS include its use as a silicon source in the semiconductor industry for depositing silicon dioxide films, and in materials science for the sol-gel synthesis of silica, aerogels, and advanced coatings. Its versatility also extends to its use as a crosslinking agent in silicone polymers and as a component in specialized industrial binders.
