Product Description
Product Description
Silicon tetrachloride (SiCl4) is a chemical compound that exists as a gas at room temperature and pressure. It is a colorless, volatile liquid when condensed, but it quickly evaporates to form a gas. Silicon tetrachloride is primarily used in the production of silicon and silicon-based compounds.
Here are some key properties and uses of silicon tetrachloride gas:
- Chemical Formula: SiCl4
- Molecular Weight: 169.90 g/mol
- Physical State: Gas at room temperature and pressure
- Odor: It has a pungent and suffocating odor.
- Density: The density of silicon tetrachloride gas is higher than air, so it tends to settle near the ground.
- Solubility: Silicon tetrachloride is soluble in some organic solvents but not in water.
- Reactivity: It is highly reactive and reacts readily with water to form hydrochloric acid and silicic acid. The reaction with water is exothermic and produces fumes.
SiCl4 + 2H2O -> Si(OH)4 + 4HCl - Toxicity: Silicon tetrachloride is toxic and can cause severe irritation to the eyes, skin, and respiratory system. It should be handled with appropriate precautions in a well-ventilated area.
- Uses:
- Production of silicon: Silicon tetrachloride is a key intermediate compound used in the production of elemental silicon. It is reacted with high-purity molten magnesium to produce magnesium chloride and elemental silicon.
- Chemical synthesis: It is used as a precursor in the synthesis of various silicon-based compounds, including silicones, silanes, and high-purity silicon.
- Catalyst: Silicon tetrachloride can act as a catalyst in certain chemical reactions, such as Friedel-Crafts reactions.
- Electronics industry: It is used in the production of semiconductors and other electronic components.
- Optical coatings: Silicon tetrachloride is employed in the deposition of thin films for optical coatings on glass and other substrates.
It's important to note that silicon tetrachloride is a hazardous substance, and proper safety measures should be followed when handling or working with it.
