WebSilicon tetrafluoride was obtained by the thermal decomposition of pure-grade sodium hexafluorosilicate and purified by low-temperature distillation. Next, SiF 4 was 28 Si-enriched by centrifugation and converted to silane by calcium hydride reduction. To remove hydrocarbons, the silane was distilled. Download to read the full article text. 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.
