What is a Silicon tetrachloride (SiCl₄)?

Silicon tetrachloride (SiCl₄) is an inorganic compound consisting of silicon and chlorine, with the chemical formula SiCl₄. It is a colorless, transparent liquid at room temperature and has a strong, pungent odor. SiCl₄ is highly reactive and reacts with water to produce silica gel and hydrochloric acid. This compound is used in various applications, particularly in the semiconductor industry, where it plays a key role in the production of silicon wafers. In organic chemistry, SiCl₄ is used for the synthesis of silicon-based compounds. It is also utilized in the production of silicon-based glass, ceramics, and silicone products. Additionally, SiCl₄ is employed in the formation of silicon oxide films, making it essential in the manufacturing of electronic devices. It can act as a catalyst in certain chemical reactions, particularly in organic synthesis. Silicon tetrachloride is also used as a precursor to silica (SiO₂), which is found in glass, concrete, cosmetics, pharmaceuticals, and food additives. Due to its reactivity with water and the production of strong acids, SiCl₄ requires careful handling and storage in specialized equipment.
