Electronic Devices Semiconductor Industry Production Usage Sihcl3 Trichlorosilane (TCS)

Product Description

SiHCl3 refers to trichlorosilane, which is a chemical compound composed of one silicon atom bonded to three chlorine atoms and one hydrogen atom. Here are some key points about SiHCl3:

1. Chemical Formula: SiHCl3
2. Molecular Weight: 135.4 g/mol
3. Structure: Trichlorosilane has a tetrahedral molecular geometry, with the silicon atom at the center and three chlorine atoms and one hydrogen atom arranged around it.
4. Physical Properties: Trichlorosilane is a colorless liquid at room temperature. It has a pungent odor and is highly volatile.
5. Production: Trichlorosilane is primarily produced by the reaction of metallurgical-grade silicon with hydrogen chloride gas. It is an intermediate product in the production of high-purity silicon for electronics and solar cell applications.
6. Chemical Reactivity: Trichlorosilane is reactive and can undergo various chemical reactions. It can react with water to produce hydrogen chloride gas and silicic acid. It can also react with other compounds to form silicon-containing products.
7. Applications: Trichlorosilane is a key precursor in the production of silicon for the electronics and solar industries. It is used to produce high-purity silicon wafers for semiconductor devices and photovoltaic cells. Trichlorosilane is also used in the production of silicones, which have a wide range of applications, including as sealants, adhesives, lubricants, and coatings.
8. Safety Considerations: Trichlorosilane is a corrosive and toxic substance. It can cause severe burns upon contact with the skin or eyes and can release toxic hydrogen chloride 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: Trichlorosilane 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: Trichlorosilane 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.
