Definition of the Tantalum Element
A very hard, heavy, gray
metallic element that is exceptionally resistant to chemical
attack below 150°C. It is used to make light-bulb filaments,
electrolytic capacitors, lightning arresters, nuclear reactor
parts, and some surgical instruments. The element has a melting
point exceeded only by tungsten and rhenium. Tantalum has the most
capacitance per volume of any substance.
Origin / Meaning of the name Tantalum
The name originates from King Tantalus, the father of Niobe, in
Greek mythology.
Classification of the Tantalum Element
Tantalum is
classified as a "Transition Metal" which are located in Groups 3 -
12 of the Periodic Table. An Element classified as a Transition
Metals is ductile, malleable, and able to conduct electricity and
heat.
Facts about the History
and the
Discovery of the Tantalum
Element
Tantalum was discovered by
Anders Ekeberg
in 1802. The element was isolated in 1820 by Jons Berzelius. The
first relatively pure ductile metal was produced in 1903 by
Werner von Bolton.
Occurrence the Tantalum Element
Obtained from the minerals tantalite, euxenite, samarskite, and
fergusonite
Mined in Australia, Brazil, Canada, Africa, Portugal, and
Thailand.
