Silicon tetrachloride or tetrachlorosilane is the inorganic compound with the formula SiCl 4. It is a colorless volatile liquid that fumes in air. It is used to produce high purity silicon and silica for commercial applications.
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.
Trichlorosilane (TCS) is an inorganic compound with the formula HCl 3 Si. It is a colourless, volatile liquid. 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.
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!
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
A notable derivative of GeCl 4 is germanium dioxide.In the manufacture of optical fibers, silicon tetrachloride, SiCl 4, and germanium tetrachloride, GeCl 4, are introduced with oxygen into a hollow glass preform, which is carefully heated to allow for oxidation of the reagents to their respective oxides and formation of a glass mixture.
Tetrakis(trimethylsilyl)silane is the organosilicon compound with the formula (Me 3 Si) 4 Si (where Me = CH 3). It is a colorless sublimable solid with a high melting point. The molecule has tetrahedral symmetry. The compound is notable as having silicon bonded to four other silicon atoms, like in elemental silicon.
