Web6.3 Pyrophoric Gases-Silane Gas vessels with more than 0.5 scf (14L) of silane content above 1.37% by volume are regulated by CGA G-13. The required engineering controls for silane are much more extensive than required for flammable gases. Silane design experts should be consulted. 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 …

WebApr 15, 2024 · With the increasing importance of environmental protection, high-performance biopolymer films have received considerable attention as effective alternatives to petroleum-based polymer films. In this study, we developed hydrophobic regenerated cellulose (RC) films with good barrier properties through a simple gas–solid … 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).
