Rhodium: uses

The following uses for rhodium 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).

  • alloying agent to harden platinum and palladium. Such alloys are used for furnace windings, thermocouple elements, bushings for glass fibre production, electrodes for aircraft spark plugs, and laboratory crucibles
  • used as an electrical contact material as it has a low electrical resistance, a low and stable contact resistance, and is highly resistant to corrosion
  • plated rhodium produced by electroplating or evaporation is exceptionally hard and is used for optical instruments
  • used for jewellery
  • industrial catalyst
  • rhodium is used as part of the catalytic system in car catalytic converters, used to clean up exhaust gases to some extent
