설명

일반 설명

Tetraethyl orthosilicate (TEOS) is an inorganic material used as a precursor for the synthesis of silica-based materials by methods such as sol gel technique, due to its high affinity to water. It can also be used in the synthesis of blended membranes.

애플리케이션

Commonly used as a precursor to prepare xerogel

TEOS is majorly used as a silicon source in the synthesis of silicon oxide which can be further used in a variety of optoelectronics based applications. It can also be used in the formation of hybrid coatings for potential usage in corrosion protection.

Will interact with dodecylamine in the formation of intercalation compounds of H⁺-magadiite and used in a study of mixed-metal bioactive glasses.
