SILICON TETRACHLORIDE, molecular formula SiCl4, a kind of colorless or yellowish smoking liquid, it's an inorganic chloride of silicon. Purified silicon tetrachloride is widely used in the manufacture of silicone esters, organic silicone oil, high temperature insulating paint, silicone rubber and heat resistant pad lining materials and other silicone compounds. The high purity silicon tetrachloride is the main raw material for the manufacture of fumed silica, optical fiber preform rod, polysilicon, quartz fiber and high-end silicon nitrode, which is an essential and important chemical raw material in large-scale industrial production.

With the rapid development of localization in both high-end fumed silica and optical fiber preform rod, the domestic demand for high purity silicon tetrachloride will expand day by day.
