Top 13 interesting facts about Tantalum

  • Tantalum was discovered in 1802 by Anders Ekeberg. Its name derives from the name of the mythological Greek king Tantalus.
  • Tantalum's melting point is at 2996.0 C (3269.15 K, 5424.8 F) and its boiling point is at 5425.0 C (5698.15 K, 9797.0 F).
  • Tantalum is a very rare element.
  • Tantalum is hard, gray, and lustrous transition metal.
  • Tantalum is very resistant to corrosion and below 150 centigrade it is almost completely immune to corrossion.
  • Tantalum is very good conductor of heat and electricity.
  • Tantalum is very dense and ductile metal.
  • Tantalum is member of the refractory metals group.
  • Tantalum has similar properties with niobium.
  • Tantalum is found together with niobium in minerals tantalite, columbite, and coltan.
  • Tantalum has only one stable isotope: 181-Tantalum.
  • Tantalum is mainly produced in Australia, Brazil, Canada, China, Ethiopia, Thailand, and Malaysia.
  • Tantalum is used in many industrial applications but the most important are: in electronics, in alloys with high melting points, in production of vacuum furnace parts, thermowells, precious watches, in orthopedic implants, and in camera lenses.
