Trichlorosilane
Trichlorosilane is a chemical compound containing silicon, hydrogen, and chlorine. At high temperatures, it decomposes to produce silicon, and as such, 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. Additional recommended knowledgeProductionIndustrially, trichlorosilane is produced by blowing hydrogen chloride through a bed of silicon powder at 300°C. There, they combine to make trichlorosilane and hydrogen according to the chemical equation
A properly designed reactor can achieve a yield of 80-90% trichlorosilane. The major byproducts are silicon tetrachloride (chemical formula SiCl4), hexachlorodisilane (Si2Cl6), and dichlorosilane (H2SiCl2), from which trichlorosilane can be separated by distillation. The reverse process is used to produce of silicon of higher purity. References|Semiconductors: Silicon: Substrate Manufacture: Polycrystalline Silicon Production External links |
