Chromium: uses

The following uses for chromium are gathered from a number of sources as well as from anecdotal comments. I'd be delighted to receive corrections as well as additional referenced uses (please use the feedback mechanism to add uses).

  • used to harden steel, to manufacture stainless steel, and to form alloys
  • used in plating to produce a hard, beautiful surface and to prevent corrosion.
  • used to give glass an emerald green colour. It is responsible for the green colour of emeralds and the red colour of rubies
  • wide use as a catalyst
  • dichromates such as K2Cr2O7 are oxidising agents and are used in quantitative analysis and also in tanning leather
  • lead chromate as chrome yellow is a pigment
  • compounds are used in the textile industry as mordants
  • used by the aircraft and other industries for anodising aluminium
  • the refractory industry uses chromite for forming bricks and shapes, as it has a high melting point, moderate thermal expansion, and stable crystalline structure
  • tanning leather
