Project Introduction: Trichlorosilane, also named Silicochloroform ,is mainly used in the synthesis of organic silicone, alkyl, aryl and organic functional group chlorosilane. It's the most basic monomer of the organic silane coupling agent,and the production material for semiconductor silicon and silicon; Manufacturing process of the tetrachlorosilane includes the reciprocal effect by the trichlorosilane steam and the hydric steam which has been heated up to 1700-2500SiCK by the plasma accelerator; the steam compound in the reactor goes into the condensing system that separates trichlorosilane. After that, polycrystalline silicon can be made.
