Ethyl silicate, also known as tetraethyl orthosilicate, tetraethyl silicate, or tetraethoxysilane, has a molecular formula of Si (OC2H5) 4. It is a colorless and transparent liquid with a special odor. Stable in the absence of water, it decomposes into ethanol and silicic acid when in contact with water. It becomes turbid in humid air and becomes clear again after standing, resulting in the precipitation of silicic acid. It is soluble in organic solvents such as alcohols and ethers.

Ethyl silicate can be used as an insulation material, coating, zinc powder coating adhesive, optical glass processing agent, coagulant, organic silicon solvent, and precision casting adhesive for the electronics industry. It can also be used to manufacture model boxes for metal investment casting methods; After complete hydrolysis of ethyl silicate, extremely fine silica powder is produced, which is used to manufacture fluorescent powder; Used for organic synthesis, preparation of soluble silicon, preparation and regeneration of catalysts; It is also used as a crosslinking agent and intermediate in the production of polydimethylsiloxane.
