Sif4 chemistry
Silicon tetrafluoride or tetrafluorosilane is a chemical compound with the formula SiF4. This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point. It was first prepared in 1771 by Carl Wilhelm Scheele by dissolving silica in hydrofluoric acid. , later … See more SiF 4 is a by-product of the production of phosphate fertilizers wet process production, resulting from the attack of HF (derived from fluorapatite protonolysis) on silicates, which are present as impurities in the See more This volatile compound finds limited use in microelectronics and organic synthesis. It's also used in production of fluorosilicic acid (see … See more In 2001 it was listed by New Jersey authorities as a hazardous substance that is corrosive and may severely irritate or even burn skin and eyes. It is fatal if inhaled. See more Volcanic plumes contain significant amounts of silicon tetrafluoride. Production can reach several tonnes per day.
