Basic Information
Product Name: Tetraethyl orthosilicate (abbreviated as TEOS)
CAS Number: 78-10-4
Chemical Formula: C8H20O4Si
Molecular Weight: 208.33
Appearance: It is a colorless and transparent liquid with a special odor.
Density: 0.934 - 0.944 g/cm³.
Melting Point: -77 °C.
Boiling Point: 168.1 °C.
Solubility: It is slightly soluble in water and miscible with organic solvents such as ethanol and ether. It gradually hydrolyzes into silica sol in humid air.
Uses
Coating Industry: It is used to manufacture coatings that are resistant to chemical corrosion and heat. It can also be used as a coating additive to improve the adhesion, hardness, and water resistance of coatings.
Electronics Industry: It is an important raw material for preparing silicon dioxide films in the semiconductor industry. High - quality silicon dioxide insulating layers are formed on substrates such as silicon wafers by methods such as chemical vapor deposition.
Ceramics Industry: As a precursor of ceramic materials, it is used to prepare high - performance ceramics such as silicon nitride ceramics and silicon carbide ceramics. It can improve the properties of ceramics, increasing their density and mechanical strength.
Adhesives: It can enhance the adhesive force of adhesives to inorganic materials and is often used to prepare inorganic adhesives.
Catalyst Support: It can be used as a precursor of catalyst supports. Silica supports with high specific surface area and good pore structure are prepared through hydrolysis and polycondensation reactions, which are widely used in catalytic reactions in the petrochemical and fine chemical industries.
Safety Information
Toxicity: Tetraethyl orthosilicate is irritating to the eyes, skin, and respiratory tract. Inhalation or ingestion may cause damage to the body and has an inhibitory effect on the central nervous system.
Flammability and Explosiveness: It is flammable. Its vapor can form an explosive mixture with air. It can cause combustion and explosion when exposed to open fire and high heat. It can react with oxidants.
Storage Precautions: Store in a cool, dry, and well - ventilated warehouse. Keep away from fire and heat sources. The warehouse temperature should not exceed 37 °C. Keep the container sealed. It should be stored separately from oxidants, acids, alkalis, etc. Do not store them together. Use explosion - proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with leak - emergency - handling equipment and suitable containment materials.
