Trichlorosilane is a chemical compound containing silicon, hydrogen, and chlorine. At high temperatures, it decomposes to produce silicon, and therefore purified trichlorosilane is the principal source of ultrapure silicon in the semiconductor industry. In water, it rapidly decomposes to produce a silicone polymer while giving off hydrochloric acid. Because of its reactivity and wide availability, it is frequently used in the synthesis of silicon-containing organic compounds.

SiSiB® PC5030 is a clear liquid with acrid odor of hydrogen chlori

SiSiB® PC5030 is an important raw material for many silane coupling agents.

SiSiB® PC5030 is an intermediate in the production of ultrapure silicon in the semiconductor industry. Chlorosilanes obtained from crude silicon are purified by fractional distillation techniques and then reduced with hydrogen to give silicon of 99.999999999 % (11 nines) purity.

SiSiB® PC5030 is an important raw material for polycrystalline silicon.
