Rare Earth Alloys
The rare earth metals are a set of seventeen metallic elements that include the fifteen lanthanides on the periodic table plus scandium and yttrium moderately abundant in the earth's crust, with unique properties essential to high-technology products. Rare earth metals include:
15 lanthanides
- Lanthanum (La)
- Samarium (Sm)
- Holmium (Ho)
- Promethium (Pm)
- Cerium (Ce)
- Europium (Eu)
- Erbium (Er)
- Dysprosium (Dy)
- Praseodymium (Pr)
- Gadolinium (Gd)
- Thulium (Tm)
- Lutetium (Lu)
- Neodymium (Nd)
- Terbium (Tb)
- Ytterbium (Yb)
2 group IIIB elements
- Scandium (Sc)
- Yttrium (Y)
Rare earth metals are used in metallurgy, polishing, and the creation of catalysts and magnets, with a range of applications including automobile and petroleum refining, phosphors for flat panel displays in cell phones and laptops, permanent magnetics, and rechargeable batteries. Rare earth metals are also vital in defense applications such as fighter jet engines, missile guidance systems, lasers, and satellite communications systems [1].
