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.
