WebJan 27, 2024 · Tetraethyl orthosilicate (TEOS) is extensively used in the conservation of stone-built cultural heritage, which is often subjected to water-induced degradation … Tetraethyl orthosilicate, formally named tetraethoxysilane (TEOS), ethyl silicate is the organic chemical compound with the formula Si(OC2H5)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 … See more TEOS is mainly used as a crosslinking agent in silicone polymers and as a precursor to silicon dioxide in the semiconductor industry. TEOS is also used as the silica source for synthesis of some See more TEOS easily converts to silicon dioxide upon the addition of water: Si(OC2H5)4 + 2 H2O → SiO2 + 4 C2H5OH An idealized equation is shown, in reality the silica produced is hydrated. This hydrolysis reaction … See more • NIST Standard Reference Database 69, June 2005 Release: NIST Chemistry WebBook • CDC – NIOSH Pocket Guide to Chemical Hazards See more TEOS is stored in hermetic steel vessels at temperatures up to 30°С. See more TEOS has low toxicity by ingestion. While tetramethoxysilane is highly damaging to eyes since it deposits silica, TEOS is much less so due to lower hydrolysis rate of the ethoxy groups.
