The Significance of Rare Earth Elements

Rare earth metals (REM) and rare earth elements (REE) are the collection of 17 earth elements in the periodic table, namely scandium, yttrium, and 15 lanthanides. Because of their unique magnetic, fluorescent and chemical properties, REM and REE are key materials used in scientific innovation.

  • Scandium
  • Yttrium
  • Lanthanum

For example

Major rare earth applications areused in hybrid vehicles. For example the Toyota Prius, contains 30 kg (65 lb) of REE. Rare earth elements areused in motors, metal hydride batteries, glass, autocatalysts, and electronics.

Principal Uses

Lanthanum Re-chargeable batteries
Cerium Catalysts, glass, polishing
Praseodymium Magnets, glass colourant
Neodymium Magnets, lasers, glass
Samarium Magnets, lighting, lasers
Europium TV Colour phosphors: red
Terbium Phosphors: green, magnets
Dysprosium Magnets, lasers
Gadolinium Magnets, superconductors
Yttrium Phosphors, ceramics, lasers

Details

There are 15 accepted rare earth elements known as the lanthanides with atomic numbers 57 to 71 and are listed as follows: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, and ytterbium.



Promethium is a synthetic element, which does not occur naturally is not generally included as a commodity.
Yttrium is considered a rare earth since it tends to occur in the same ore deposits as the lanthanides and exhibits similar chemical properties.

It has been the practice to report rare elements as a percentage oxide.

The elements are initially reported from the lab in parts per million. The elements are converted to oxides with the following molecular formulas, La2O3, Ce2O3, Pr2O3, Nd2O3, Sm2O3, Eu2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3, Lu2O3, and Y2O3.

Rare earth oxides are reported as total rare earth oxides (TREO) which is a simple addition of the percentages of the above 15 components

Rare earth oxides are further classified as light rare earth oxides (LREO) and heavy rare oxides (HREO)
