What Are Rare Earth Materials? Definitions & Context

Rare earth materials (often called rare earth elements or REEs) are a group of 17 chemically similar elements: the 15 lanthanides found in row 6 of the periodic table, plus scandium and yttrium. They include:

• Lanthanum (La)
• Cerium (Ce)
• Praseodymium (Pr)
• Neodymium (Nd)
• Promethium (Pm) (rare in nature)
• Samarium (Sm)
• Europium (Eu)
• Gadolinium (Gd)
• Terbium (Tb)
• Dysprosium (Dy)
• Holmium (Ho)
• Erbium (Er)
• Thulium (Tm)
• Ytterbium (Yb)
• Lutetium (Lu)
• Scandium (Sc)
• Yttrium (Y)

Although not truly “rare” in the Earth’s crust, these elements are rarely found concentrated enough to mine economically. They often occur together, requiring complex processes to separate. Their extraction and processing determine their supply and value chains, critical for many industries.

Key Functions of Rare Earth Materials

The unique properties of rare earth materials stem from their electronic structure. As a group, REEs impart:

• Magnetic properties: Crucial for high-strength magnets in electric motors, wind turbines, and sensors.
