Silicon tetrachloride

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.

Silicon tetrachloride can be used:

• A precursor in the chemical vapor deposition (CVD) process to deposit silicon onto graphite substrates. This approach results development of high-performance anodes for lithium-ion batteries.
• A precursor material in the hydrogen thermal plasma (H-plasma) process to synthesize silicon nanospheres, which are suitable for use as anode materials in lithium-ion batteries.

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
