• Detailed Description:

  Cas No. :7783-60-0 Specs:99.0% min
  Product name: Sulfur tetrafluoride
  CAS: 7783-60-0
  Molecular formula: SF4
  Molecular weight: 108.05
  Risk label: (6) toxic
  
  SF4 Physicochemical properties:
  Boiling point: -38℃
  Melting point: -124℃
  Relative density: 1.95(liquid), 2.35(solid), 3.7(gas)
  Critical temperature: 90.9℃
  Critical pressure: 6342.9kPa
  Vapour tension (21℃): 1067kPa
  
  Under the normal temperature and pressure, SF4 is toxic and corrosive gas, which smelling is similar with SO2. It can hydrolysis when met the water in the air and produce HF white mist. Do not burn or explode. It is stable at 600℃, can be absorbed by alkali liquor and change into non-toxic salt. Can be soluble in benzene.
  
  Use
  It is the most effective, high selectivity fluridizer, can be widely used in high-end LCD materials and fluoride agrochemical, medicine and its intermediates synthesis. It also can be used for electronic gas, chemical vapor deposition, surface treated, plasma dry carved and other aspects.
