Product Description
Product Description
Silicon tetrachloride (SiCl4) is a colorless, volatile liquid compound at room temperature. It is not a gas under normal conditions, but it can easily vaporize to form a gas when exposed to air or when heated. Silicon tetrachloride is primarily used in the production of silicon, which is a key component in various electronic devices and solar panels.
Here are some key properties and uses of silicon tetrachloride:
Properties:
- Chemical formula: SiCl4
- Molar mass: 169.90 g/mol
- Physical state: Liquid at room temperature, but readily vaporizes to form a gas
- Odor: Pungent and suffocating odor
- Density: 1.48 g/cm³ (liquid state)
- Melting point: -70.9 °C (-95.6 °F)
- Boiling point: 57.6 °C (135.7 °F)
- Solubility: Reacts with water to form hydrochloric acid and silicic acid
Uses:
- Silicon production: Silicon tetrachloride is a precursor in the production of elemental silicon. It reacts with high-purity silicon to form trichlorosilane (SiHCl3), which is then reduced to produce silicon.
- Chemical intermediate: It serves as an intermediate compound in various chemical reactions to synthesize other silicon-based compounds, such as organosilicon compounds used in the production of silicone polymers and resins.
- Semiconductors: Silicon tetrachloride is employed in the semiconductor industry for the production of high-purity silicon used in electronic devices like integrated circuits and computer chips.
- Optical fibers: It is used in the manufacture of optical fibers, which are widely used for telecommunications and data transmission.
- Catalyst: Silicon tetrachloride can act as a catalyst in certain chemical reactions, such as the Friedel-Crafts reaction, which is used in the synthesis of aromatic compounds.
It's important to note that silicon tetrachloride is highly reactive and should be handled with care. It reacts violently with water, releasing hydrochloric acid fumes, so it should be stored and used in a well-ventilated area with appropriate safety measures.
