A rare-earth element (REE) or rare-earth metal (REM) is one of a set of 17 metallic elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium.

The rare-earth elements are cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb) and yttrium (Y).

Rare-earth elements are an essential input in magnets and magnetic powders, catalysts, metallurgical additives, polishing powders, phosphors, glass additives, ceramics and other engineered rare earth materials as well as batteries, motors and generators, lasers, drives, sensors, and other components and systems used in a variety of industries producing intermediate goods. In turn these products are used in health care, clean energy, automotive, lighting, communications, audio equipment, defense technologies, other electronics, advanced optics, oil refining, and a variety of other economic activity. Although the amount of REE used in a product may not be a significant part of that product by weight, volume, or value, 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.

Rotalab supplies rare-earth elements in purity ranging from 99% (2N) to 99.9999% (6N).
