Silicon (IV) iodide（Cat No.:M061949）, also known as silicon tetraiodide or SiI4 is an inorganic compound formed by the combination of silicon with iodine. This compound appears as a colorless, crystalline solid with a sharp odor, and it is highly sensitive to moisture, readily hydrolyzing in water to form hydrogen iodide and silica. Silicon (IV) iodide is primarily used in organic synthesis and as a source of high-purity silicon in semiconductor manufacturing. Its volatility and ability to decompose back into silicon and iodine make it useful in chemical vapor deposition processes.
