About Tantalum

What is tantalite/tantalum

  • Tantalite (or coltan) is a naturally occurring oxide; the main ore and source of oxides and metallic tantalum
  • Tantalum is the refined elemental metal (although mostly used as high purity oxides)

 

Properties

  • Its key attributes include: excellent electrical characteristics, extremely high melting point, strong alloying and high resistance to corrosion. 
  • Tantalum’s unique physical and chemical properties are expected to ensure high usage in new technologies.

 

Major Uses

  • Tantalum is mainly used in electronic components such as capacitors and some high-power resistors in everyday items like cell phones, personal and laptop computers, digital and video cameras, LCD/Plasma televisions, and handheld gaming devices.
  • When alloyed with other metals tantalum is used in fabricating carbide tools for metalworking equipment, jet engine components, chemical process equipment, nuclear reactors and missile parts. It’s also widely used in automotive electronics such as anti-lock braking systems (ABS), navigation systems, wheel traction control, airbag inflation, engine management and fuel economy.

 

Other Uses

  • Fabrication of surgical instruments and implants
  • Chemical reaction vessels and pipes for corrosive liquids
  • Heat exchanging coils
  • Fabrication of high refractive index glass for camera lenses
  • Production of vacuum furnace parts
  • Fabrication of components for chemical plants, nuclear power plants, airplanes and missiles
