Rare earths

A rare earth element or metal includes the fifteen lanthanides as well as scandium and yttrium. These elements are quite common within the Earth’s crust, however, they tend to be widely distributed due to their properties. There was approximately *** million metric tons of rare earth reserves worldwide as of 2013, with ** million metric tons located in China alone. Rare earth oxides in particular are usually an opaque black or dark brown color and often streaked with brown. They are also often coated in an earthy surface alteration which is part of the mineral.

Rare earth metals are often used within the nuclear industry for practical and experimental applications. They can also be used for ceramics, dyes, lasers, and electric components.
