Rare Earth Elements​

What are rare earth elements, and why are they important?

Rare earth elements (REEs) are the 17 elements including the 15 lanthanide elements;

Cerium, Dysprosium, Erbium, Europium, Gadolinium, Holmium, Lanthanum, Lutetium, Neodymium, Praseodymium, Promethium, Samarium, Terbium, Thulium, Ytterbium, Yttrium and Scandium. Yttrium and Scandium are included within REEs since they are often found together with lanthanide elements and demonstrate similar properties. Given all these elements are metals, they are also often called rare earth metals.

Rare earth elements are an essential part of many high-tech devices. The U.S. Geological Survey news release “Going Critical” explains: “Rare-earth elements (REE) are necessary components of more than 200 products across a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and televisions. Significant defense applications include electronic displays, guidance systems, lasers, and radar and sonar systems. Although the amount of REE used in a product may not be a significant part of that product by weight, value, or volume, the REE can be necessary for the device to function. For example, magnets made of REE often represent only a small fraction of the total weight, but without them, the spindle motors and voice coils of desktops and laptops would not be possible.
