Product introduction
Silicon tetrafluoride (SiF4) is a kind of colorless, toxic, pungent and smelly gas with a molecular weight of 104.06. Silicon tetrafluoride is easily deliquescent and can produce thick smoke in damp air. Silicon tetrafluoride is soluble in ethanol, ether, nitric acid, hydrofluoric acid, its hygroscopicity is very strong and SiF4 changes into a liquid under pressure, silicon tetrafluoride has a wide range of applications in the electronic industry.
