Audited Supplier Tetraethoxysilane (also known as tetraethyl orthosilicate or TEOS) is a chemical compound with the formula Si(OC2H5)4. It is a clear, colorless liquid that is primarily used as a precursor in the production of various silicon-based materials, particularly silicon dioxide (SiO2) and silica gel.
TEOS is widely employed in the semiconductor industry, where it is used as a source of silicon for the deposition of thin films of SiO2. These films are used as insulating layers or as passivation coatings on electronic devices such as integrated circuits. TEOS is favored in this application due to its high purity and its ability to form high-quality and uniform films at relatively low temperatures.
In addition to its semiconductor applications, tetraethoxysilane is also used as a cross-linking agent in the production of hybrid organic-inorganic materials known as sol-gels. Sol-gels are formed by hydrolysis and condensation reactions of TEOS, leading to the formation of a three-dimensional network of silica. These materials have a wide range of applications, including coatings, optical devices, catalyst supports, and biomedical materials.
When handling tetraethoxysilane, it is important to exercise caution as it is a highly reactive and volatile compound. It can cause irritation to the skin, eyes, and respiratory system upon direct contact or inhalation. Proper safety measures should be followed, including the use of appropriate personal protective equipment and working in a well-ventilated area.
