Quick Information

  • Place of Origin: China
  • CAS No. : 7783-60-0
  • Purity : 99%


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.
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.
