Product Description

CAS 10025-78-2 Trichlorosilane(STC)

Trichlorosilane, also known as trichlorosilane and silicon chloroform, is used as a raw material for high-molecular organic silicon compounds.

Trichlorosilane is not only an important intermediate for the manufacture of silane coupling agents and other organic silicon products, but also the main raw material for manufacturing polysilicon. Silane coupling agent is an important, high-tech, high value-added silicone composite material. It can cross-link cure or modify non-cross-linked resin through silane coupling agent. Therefore, it is used in glass fiber, casting and tires. Rubber and other industries have been increasingly used. Silicon tetrachloride, the main by-product of the production of trichlorosilane, is also the main raw material for the production of organic silicon. Its finished products include silicates, silicone oils, high-temperature insulating paints, organic silicon resins, silicon rubber, and heat-resistant pad lining materials, etc. . High-purity silicon tetrachloride is also an important raw material for producing high-purity silica, inorganic silicon compounds, quartz fibers, and optical fibers.


(1) Solar cells can be made to convert radiation energy into electrical energy; 

(2) High-purity crystalline silicon is an important semiconductor material; 

(3) Metal-ceramics and important materials for space navigation; 

(4) ) Optical fiber communication, the latest modern communication means; 

(5) Silicon organic compounds with excellent performance.

Used to compose the organosilane alkyl and chlorosolane. It is the basic monomer of silane coupling agent, and the material of producing the semiconductor silicon and polysilicon.
