China Supply Best Price High Purity Industrial Sicl4 Silicon Tetrachloride

Product Description

Silicon tetrachloride, commonly referred to 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. Chemical Reactivity: Silicon tetrachloride is highly reactive and readily reacts with water to form hydrochloric acid and silicic acid. It is also reactive with alcohols, amines, and other nucleophilic compounds.
6. Production: Silicon tetrachloride is primarily produced by the reaction of silicon dioxide (silica) with carbon and chlorine at high temperatures. It is also obtained as a byproduct in the production of silicon metal and silicon wafers.
7. Applications: Silicon tetrachloride has several industrial applications. It is commonly used as a precursor in the production of silicon-based materials, such as silicones, silanes, and high-purity silicon. It is also used in the manufacturing of optical fibers, as a catalyst in certain chemical reactions, and as a starting material for the synthesis of various organosilicon compounds.
8. Safety Considerations: Silicon tetrachloride is corrosive, toxic, and can cause severe burns upon contact with the skin, eyes, or mucous membranes. It should be handled with appropriate safety precautions, including the use of protective equipment and proper ventilation.
9. Environmental Impact: Silicon tetrachloride can be harmful to the environment if released without proper containment or treatment. It is important to follow appropriate waste management practices to prevent its release into the environment.
