What is Neodymium?

Neodymium is a rare earth metal that is typically found mixed with other lanthanides and therefore requires refining. Neodymium can be found in everyday equipment such as televisions, fluorescent and energy efficient lamps, and even colored glass, which can be tinted in varying shades of red. A large portion of neodymium is mined in China, and with export restrictions, global supply has become cause for concern. Fortunately, the metal is also found in the US, Brazil India and Australia, with production expected in the near future.

Neodymium is a prime component in the creation of strongest permanent magnets called “neo-magnets,” and can be found in computer data storage and loudspeakers, and even in energy efficient, wind and tidal electricity turbine generators. Neo-magnets, unfortunately, like most magnets, lose their magnetism at high temperatures, thus reducing their usability in applications that generate a high heat, like electric or hybrid vehicles. However, high-temperature neo-magnets can be made by adding terbium or dysprosium to the neodymium, thereby enabling these magnets for use in electric and hybrid vehicles.
