WebNov 15, 2024 · The highly purified trichlorosilane can be directly converted back to polysilicon by the Siemens process, or it can be reacted to form silane. The silane can be thermally decomposed to polysilicon by a FB process. WebThe silane produced by this route can be thermally decomposed to produce high-purity silicon and hydrogen in a single pass. Other industrial routes to silane involve reduction of SiF4 with sodium hydride (NaH) or reduction of SiCl4 with …

The silane produced by this route can be thermally decomposed to produce high-purity silicon and hydrogen in a single pass. Still other industrial routes to silane involve reduction of silicon tetrafluoride(SiF4) with sodium hydride(NaH) or reduction of SiCl4with lithium aluminum hydride(LiAlH4). See more Silane (or Silicane) is an inorganic compound with chemical formula, SiH4. It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, somewhat similar to that of acetic acid. Silane is of practical interest as a … See more Commercial-scale routes Silane can be produced by several routes. Typically, it arises from the reaction of hydrogen chloride with magnesium silicide: It is also prepared from metallurgical-grade silicon in a two-step process. First, silicon is treated with See more A number of fatal industrial accidents produced by combustion and detonation of leaked silane in air have been reported. Due to weak bonds and hydrogen silane is a pyrophoric gas (capable of autoignition at temperatures below 54 °C or 129 °F). See more • Haynes, William M., ed. (2011). CRC Handbook of Chemistry and Physics (92nd ed.). CRC Press. ISBN 978-1439855119. See more Silane is the silicon analogue of methane. Because of the greater electronegativity of hydrogen in comparison to silicon, this Si–H bond polarity … See more While diverse applications exist for organosilanes, silane itself has one dominant application, as a precursor to elemental silicon, particularly in the semiconductor industry.
