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

半导体级

Features and Benefits

Silicon tetrachloride exhibits:
  • High Purity (99.998%): Ensures minimal contamination, crucial for optics and photonics applications
  • Ideal for Semiconductor applications: Its ultra-high purity supports fabrication of advanced integrated circuits, wafers, and solar cells
