Top 10 interesting facts about Barium

  • Barium was discovered in 1808 by Sir Humphrey Davy. Its name derives from the Greek word "barys" which means "heavy".
  • Barium's melting point is at 725.0 C (998.15 K, 1337.0 F) and its boiling point is at 1140.0 C (1413.15 K, 2084.0 F).
  • Barium is a soft silvery metal.
  • Barium is a very reactive element.
  • Barium is never found freely in nature.
  • Barium has a very good electrical conductivity.
  • The most common minerals of barium are barite and witherite.
  • Barium is used to scavenge air in vacuum tubes, in high-temperature superconductors and electro ceramics, in steel to reduce the size of carbon grains, in fireworks, oil industry, as an x-ray agent, etc.
  • Barium has seven stable isotopes (50 isotopes are known).
  • China, India, Morocco, and the USA are the main producers of barite.
