Top 23 interesting facts about Cerium

  • Cerium was discovered in 1803 by Wilhelm von Hisinger, Martin Heinrich Klaproth, and Jons Jakob Berzelius. Its name derives from the word "Ceres" which is a dwarf planet and it is the name of the Roman goddess of agriculture.
  • Cerium's melting point is at 795.0 C (1068.15 K, 1463.0 F) and its boiling point is at 3257.0 C (3530.15 K, 5894.6 F).
  • Cerium is a soft, malleable, and ductile metal.
  • Cerium has a silvery color.
  • Cerium oxidizes in the air.
  • Cerium reacts with water.
  • Cerium metal is highly pyrophoric (it burns when scratched).
  • Cerium is the most abundant among the Rare Earth elements.
  • Cerium is mostly found in monazite and bastnasite.
  • Cerium has the third longest liquid range of all elements.
  • Cerium has four naturally occurring isotopes: 140-Ce (more than 88% of Earth's cerium), 142-Ce, 138-Ce, and 136-Ce.
  • Only 140-Ce is stable.
  • Cerium is used as catalytic converter and fuel additive in automotive industry.
  • Cerium oxide is used in self cleaning ovens as a hydrocarbon catalyst and as an agent for precision polishing optics.
  • Cerium compounds are important components in glass production.
  • Cerium is used in TV screens and fluorescent lamps.
  • Cerium is used in various aluminum and iron alloys.
  • Cerium alloys are used in permanent magnets.
  • An average size human body contains 40 milligrams of cerium.
  • Cerium salts can stimulate metabolism.
  • Cerium accumulates in bones (like calcium does).
  • Cerium has a low to moderate toxicity.
  • Cerium is more dangerous to aquatic organism than it is to humans.
