General description
Silicon tetrachloride is a highly reactive and volatile inorganic compound widely utilized as a precursor in both solution-based and vapor-phase deposition processes. It plays a critical role in the synthesis of high-purity silicon-based materials such as silicon dioxide (SiO2) and silicon nitride (Si₃N₄), which are essential in a broad range of high-performance applications such as semiconductor industry, optics and photonics. Additionally, it is also used in the manufacture of high-purity silica glass, advanced ceramics, and energy storage components.
Application
半導体グレ-ド。
