Trichlorosilane is not only an important intermediate of silane coupling agent and other organic silicon products, but also the main raw material of polysilicon. Silane coupling agent is an important, high-tech content, high added value of silicone composite materials, through the silane coupling agent can make non-crosslinked resin to achieve crosslinking curing or modification, so in glass fiber, casting, tire rubber and other industries has been increasingly widely used. The main by-product of the production of trichlorosilane tetraclorosilane is also the main raw material of the manufacturing of silicone, its finished products are silicone ester, silicone oil, high temperature insulating paint, silicone resin, silicone rubber and heat resistant cushion materials. High purity silicon tetracloride is also an important raw material for manufacturing high purity silicon dioxide, inorganic silicon compound, quartz fiber and optical fiber.
The main uses of polysilicon products :(1) can be made into solar cells, the radiation energy into electric energy; (2) High purity crystalline silicon is an important semiconductor material; (3) cermets, important materials for space travel; (4) Optical fiber communication, the latest modern means of communication; (5) silicone organic compound with excellent performance.
