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.
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.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
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 (SiCl₄) 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 ...
