What is Silicon Tetrafluoride？

Silicon tetrafluoride or Tetrafluorosilane is the actinic admixture with the blueprint SiF4. This tetrahedral atom is notable for accepting a appreciably attenuated aqueous ambit (its baking point is alone 4 °C aloft its melting point). It was aboriginal actinic by John Davy in 1812.

Silicon Tetrafluoride is a by-product of the assembly of phosphate fertilizers, consistent from the advance of HF (derived from fluorapatite protonolysis) on silicates. In the laboratory, the admixture is able by heating BaSiF6 aloft 300 °C, whereupon the solid releases airy SiF4, abrogation a balance of BaF2. The appropriate BaSiF6 is able by alleviative aqueous hexafluorosilicic acerbic with barium chloride. The agnate GeF4 is able analogously, except that the thermal "cracking" requires 700 °C.
