orthosilicate(Ethyl Silicate) is the chemical compound with the
formula Si(OC2H5)4. Often abbreviated TEOS, this molecule consists
of four ethyl groups attached to SiO44- ion, which is called
- Synonyms of TEOS are
ethyl silicate, silicic acid, tetraethyl ester, silicon ethoxide.
- TEOS can be considered
to be the ethyl ester of orthosilicic acid, Si(OH)4. It is a
- TEOS is a tetrahedral
molecule. Many analogues exist, and most are prepared by alcoholysis
of silicon tetrachloride.
- Ethyl Silicate has the
remarkable property of easily converting into silicon dioxide. This
reaction occurs upon the addition of water.
- TEOS is mainly used as
a cross linking agent in silicone polymers and as a precursor to
silicon dioxide in the semiconductor industry.
- The ethyl silicate
polymer is produced by a two step addition of catalysts wherein a
hydrolysis catalyst, for example, hydrochloric acid is added
initially and a second catalyst, such as phosphonitrilic chloride
trimer is added subsequently.
- A TEOS-based, sol-gel
glass composition with additives selected for various applications.
- The composition
is made by mixing ethanol, water and TEOS adjusting the pH into the
acid range and aging the mixture at room temperature. The additive
such as optical indicator are then added to the mixture to form the
composition which can be applied to a substrate before curing.
- The Si-containing
alkoxide(TEOS) undergoes hydrolysis and polymerization reactions to
form silica gel, which reduces the volume of pore spaces.
- Ethyl silicate is
considered as a substance which is used in the modification of
anticorrosive coating, cross-linking agent, adhesive, dehydrant,
catalyst framework, or used in the making of high pure super-fine
- These are frequently
used to elaborate coatings based on metallic zinc for the
anticorrosive protection of substrates of iron and steel.
- Ethyl Silicates are
probably the widest used stone consolidant. After hydrolysis and
condensation, ethyl silicates originate colloidal silica that is
deposited inside the porous structure.
- The viscosity of ethyl
silicate is lower than that of water allowing for good depth of
penetration in the stone. So Ethyl silicate is used to consolidate
