Chromium(III) fluoride

Chromium(III) fluoride

Chromium trifluoride; Chromic fluoride

CAS 7788-97-8

Chemical Formula CrF3

Molecular Weight 108.99 g/mol

Chromium(III) fluoride, with the chemical formula CrF3, is a green, crystalline solid. It exists in both anhydrous and hydrated forms. The anhydrous form is relatively insoluble in common solvents but can sublime at high temperatures. Hydrates, such as [Cr(H2O)6]F3, are soluble in water and can be obtained from chromium(III) salt solutions and alkali fluorides.

Industrial Uses

1. Performance Chemicals

  • Fluorination of alkenes and alkynes: Chromium(III) fluoride can catalyze reactions that introduce fluorine atoms into organic molecules, such as double and triple bonds in alkenes and alkynes. 
  • Dehydrofluorination of fluorocarbons: It can facilitate the removal of hydrogen fluoride (HF) from fluorocarbons, which is important in producing fluorinated olefins (HFOs).
  • Precursor for chromium compounds: Chromium(III) fluoride is used to synthesize other chromium-containing materials, such as chromium oxide (Cr2O3) and chromium carbide (Cr3C2), which have various applications in materials science.

2. Metal Treatment

  • Passivation: Chromium(III) fluoride is a key component in passivating baths, which are used to create a thin, protective layer on the surface of metals. 
  • Zinc and Cadmium Alloys: These baths are specifically designed for treating zinc and cadmium alloy surfaces. 
  • Corrosion Resistance: The passivated layer formed by the chromium(III) fluoride bath helps to protect the underlying metal from corrosion, extending its lifespan. 
  • Aesthetic Improvement: The passivation process also improves the surface appearance of the treated metal.
