Tetraethyl orthosilicate, formally named tetraethoxysilane (TEOS), ethyl silicate is the organic chemical compound with the formula Si(OC 2 H 5) 4. TEOS is a colorless liquid. It degrades in water. TEOS is the ethyl ester of orthosilicic acid, Si(OH) 4. It is the most prevalent alkoxide of silicon. TEOS is a tetrahedral molecule.

Tetraethoxysilane is the main precursor material for the synthesis of zeolites and silicon dioxide, which is used in semiconductor industry. It is widely used as cross linking agents in silicon polymers and in aerogel preparations.

Tetraethoxysilane is the main precursor material for the synthesis of zeolites and silicon dioxide, which is used in semiconductor industry. It is widely used as cross linking agents in silicon polymers and in aerogel preparations. Soluble in ethanol and 2-propanol. Degrades in water.

Tetraethyl orthosilicate (TEOS) is a colorless liquid alkoxide widely used as precursor to deposition of silicon dioxide (SiO 2) thin films. It is also utilized in hydrogels, nanoparticle-based drug delivery systems, and chemical crosslinking of polymers.

2020年9月14日 · Tetraethyl orthosilicate (TEOS) is an ester of orthosilicic acid, which exists in small amounts in nature wherever silica is in contact with water. The ester is also known by several other names, including ethyl silicate (which is somewhat ambiguous), silicon tetraethoxide, and tetraethoxysilane.

As a binding agent and as a polymerization catalystTetraethoxysilane is the main precursor material for the synthesis of zeolites and silicon dioxide, which is used in semiconductor industry. It is widely used as a cross linking agent in silicon polymers and in aerogel preparations.
