Silicon tetrafluoride

CAS: 7783-61-1
Molecular Formula: SiF4
Molecular Weight: 104.0791
Product description:Colorless gas, there is a suffocating odor, poisonous! - 90.2 ℃, melting point, boiling point - 86 ℃, 95.2 ℃ sublimation. The critical temperature of 14.15 ℃. Critical pressure is 3.715 MPa. Relative density 4.69. Soluble in anhydrous ethanol, hydrofluoric acid and nitric acid, insoluble in ether. Hydrolysis in the moist air, generate hydrogen fluoride and silicate and forming of smoke, hydrolysis, under the influence of water generated orthosilicate H4SiO4 and hydrofluoric acid, the hydrolysis of hydrofluoric acid and hydrolysis of silicon tetrafluoride generate fluosilicate complexation. There is no such thing as pure fluosilicate, because of its easy decomposition, only 60% of its aqueous solution system.Preparing for fluosilicate and fluoride lead is also used as a curing agent, cement and artificial marble manufacturing pure silicon intermediate.
