Industrial Metals Buying Guide: What You Should Know About Tantalum

Have you ever heard of tantalum? Named after a Greek mythological character named Tantalos, tantalum was first discovered in 1802 by Anders Ekeberg. It’s a hard metal. When in its pure form, it can be drawn into fine wire.

Tantalum Guide

Tantalum’s symbol on the periodic table is Ta and its atomic number is 73. It has an atomic weight of 180.94788 and a melting point of 5,462.6 degrees Fahrenheit. Its boiling point is 9,856.4 degrees Fahrenheit.

Did you know that tantalum is nearly immune to chemical attacks at temperatures below 302 degrees Fahrenheit? Its oxide films are stable with good rectifying and dielectric properties.

Occurring naturally in the mineral columbite-tantalite, tantalum is found in certain countries, including Australia, Brazil, Thailand, Portugal, Nigeria and Canada.

How is tantalum used? Well, it’s used in alloys to add strength, ductility and a high melting point. Oftentimes, it’s used for electrolytic capacitors and vacuum furnace parts. It can also be found in chemical process equipment as well as nuclear reactors. Aircraft and missile parts, surgical appliances and camera lenses are some other uses where tantalum is utilized for its qualities such as being immune to body liquids and offering a high index of refraction for lenses.
