The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet for this chemical from a reliable source, it this case, noting that one should "avoid all contact! In all cases consult a doctor! ... inhalation causes sore throat and Burning sensation". [1]
Silicon tetrachloride is prepared by the chlorination of various silicon compounds such as ferrosilicon, silicon carbide, or mixtures of silicon dioxide and carbon. The ferrosilicon route is most common. [3] In the laboratory, SiCl 4 can be prepared by treating silicon with chlorine at 600 °C (1,112 °F): [1] Si + 2 Cl 2 → SiCl 4
Purified trichlorosilane is the principal precursor to ultrapure silicon in the semiconductor industry. In water, it rapidly decomposes to produce a siloxane 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. [2]
N.D. [1] Safety data sheet (SDS) ICSC 0564: Related compounds ... The trichlorosilane is then converted to a mixture of silane and silicon tetrachloride:
Silicon tetrachloride and trichlorosilane are intermediates 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 99.999 999 999 % purity.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
