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]
The rate of consumption of silicon tetrachloride is increasing due to rising demand for polysilicon around the world. Market Overview. Silicon Tetrachloride (SiClâ‚„) is a versatile chemical compound primarily used in the production of high-purity silica and optical fibers. Its applications span various high-tech industries, including ...
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.
Stock and Somieski completed the hydrolysis of dichlorosilane by putting the solution of H 2 SiCl 2 in benzene in brief contact with a large excess of water. [3] [5] A large-scale hydrolysis was done in a mixed ether/alkane solvent system at 0 °C, which gave a mixture of volatile and nonvolatile [H 2 SiO] n.
[15] [16] Above 420 °C (788 °F), silane decomposes into silicon and hydrogen; it can therefore be used in the chemical vapor deposition of silicon. The Si–H bond strength is around 384 kJ/mol, which is about 20% weaker than the H–H bond in H 2. Consequently, compounds containing Si–H bonds are much more reactive than is H 2.
Silicon tetrafluoride or tetrafluorosilane is a chemical compound with the formula Si F 4. This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point.
