Product Description

Silicon tetrachloride, also known as SiCl4, is a chemical compound composed of one silicon atom bonded to four chlorine atoms. Here are some key points about silicon tetrachloride:

1. Chemical Formula: SiCl4
2. Molecular Weight: 169.9 g/mol
3. Structure: Silicon tetrachloride has a tetrahedral molecular geometry, with the silicon atom at the center and four chlorine atoms arranged around it.
4. Physical Properties: Silicon tetrachloride is a colorless liquid at room temperature. It has a strong, pungent odor and is highly volatile.
5. Production: Silicon tetrachloride is primarily produced by the reaction of silicon with chlorine gas at high temperatures. It can also be obtained as a byproduct in the production of silicon metal or as a result of certain chemical reactions involving silicon compounds.
6. Chemical Reactivity: Silicon tetrachloride is highly reactive and readily reacts with water to produce hydrochloric acid and silica. It reacts with many other substances, including alcohols and amines, to form various silicon-containing compounds.
7. Applications: Silicon tetrachloride is used in several industrial processes. It is a precursor in the production of silicon-based materials, such as silicon metal, silicones, and silicon wafers used in the semiconductor industry. It is also used in the production of fumed silica, a fine particulate form of silicon dioxide, which finds applications as a filler, thickening agent, and in various coatings and adhesives.
8. Safety Considerations: Silicon tetrachloride is a corrosive and toxic substance. It can cause severe burns upon contact with the skin or eyes and can release toxic chlorine gas when exposed to moisture. Proper safety precautions, including the use of protective equipment and handling in well-ventilated areas, should be followed.
9. Storage and Handling: Silicon tetrachloride is typically stored and handled in sealed containers to prevent exposure to air and moisture. It should be stored away from incompatible substances and handled with care due to its reactivity and toxicity.
10. Environmental Impact: Silicon tetrachloride can have adverse effects on the environment if released without proper treatment or containment. It is important to handle and dispose of it in accordance with local regulations and best practices to minimize its impact.
