Name Origin
From king Tantalus of Greek mythology.
"Tantalum" in different languages.

Sources
Chiefly occurs in the mineral tantalite [(Fe, Mn) Ta2O6] and euxenite (as well as samarskite and fergusonite). Always found with niobium. Tantalum ores are mined in Australia, Brazil, Eqypt, Canada, Democratic Republic of Congo, Mozambique, Nigeria, Portugal, Malaysia and Thailand.
Around 840 tons are produced annually.
Uses
Used to produce metals that have high melting points, are strong and have good ductility. Alloyed with other metals, it is also used in making carbide tools for metalworking equipment and in the production of superalloys for jet engine components, chemical process equipment, nuclear reactors, and missile parts. Because of its ductility, tantalum can be drawn into fine wires or filaments, which are used for evaporating metals such as aluminium.
Tantalum pentoxide is used in capacitors, condensers, cutting tools, vacuum tube filaments and in camera lenses to increase refracting power. Because it is totally immune to the action of body liquids and is nonirritating it is widely used in making surgical appliances.
