Top 11 interesting facts about Rhodium

  • Rhodium was discovered in 1803 by William Wollaston. Rhodium's name derives from the Greek word "rhodon" that means "rose".
  • Rhodium's melting point is at 1966.0 C (2239.15 K, 3570.8 F) and its boiling point is at 3727.0 C (4000.15 K, 6740.6 F).
  • Rhodium is usually found in nature as a free metal or alloyed with similar metals.
  • Rhodium has only one naturally occurring isotope, 103-Rh.
  • Rhodium is a very rare metal (0.0002 parts per million in Earth's crust) and one of the most precious and valuable metal.
  • Rhodium is very resistant to corrosion and 80% of world's production is used for this purpose.
  • The most important sources of rhodium are located in South Africa, Ural Mountains, and North America.
  • The annual rhodium’s production is about 30 tones.
  • Usually, rhodium's price is higher than gold's price.
  • More than 80% of the rhodium's production is used in automobiles industry as a catalytic converter which transforms harmful carbon compounds emissions into less noxious gases.
  • Rhodium is also used for fiberglass production and a small amount of rhodium is used in chemical industry and jewelry industry.
