Product Description
Product Description
Silicon tetrachloride (SiCl4) is a chemical compound composed of silicon and chlorine. It is a colorless volatile liquid at room temperature, but it can also exist as a gas when heated or vaporized. Silicon tetrachloride has several industrial applications and is primarily used in the production of silicon-based materials.
Here are some key points about silicon tetrachloride gas:
- Chemical Formula: SiCl4
- Molecular Weight: 169.9 g/mol
- Physical Properties: Silicon tetrachloride is a dense liquid with a boiling point of 57.6 °C (135.7 °F) and a melting point of -68.8 °C (-91.8 °F). When heated, it vaporizes to form a colorless gas with a pungent odor.
- Production: Silicon tetrachloride is typically produced by reacting silicon with chlorine gas in the presence of a carbon-based catalyst, such as carbon tetrachloride or activated carbon.
- Industrial Uses:
- Production of Silicon: Silicon tetrachloride is a key intermediate in the production of high-purity silicon through the chemical vapor deposition (CVD) process.
- Semiconductor Industry: It is used in the manufacture of semiconductors, such as silicon wafers and chips.
- Optical Fiber Manufacturing: Silicon tetrachloride is employed in the fabrication of optical fibers, which are used in telecommunications.
- Chemical Synthesis: It serves as a precursor in the synthesis of various silicon-based compounds, including silicones, silanes, and silicates.
- Catalysts: Silicon tetrachloride is used as a catalyst in certain chemical reactions.
- Reactivity: Silicon tetrachloride is highly reactive with water, moisture, and bases. It hydrolyzes rapidly in the presence of water or humid air, forming corrosive hydrochloric acid and releasing silicon dioxide.
- Safety Considerations: Silicon tetrachloride is corrosive to the skin, eyes, and respiratory system. It should be handled with caution, and appropriate safety measures, such as wearing protective equipment, should be followed.
It's important to note that handling silicon tetrachloride requires expertise and proper safety precautions due to its reactivity and potential hazards.
