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).
Top 9 interesting facts about Rhodium
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.
