Description

Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
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.

Solubility
Soluble in ethanol and 2-propanol.

Notes
Degrades in water. Keep container tightly closed in a dry and well-ventilated place.
