What are they?
In their natural state rare earths are a group of chemically similar elements typically found in refractory minerals and difficult to isolate.
Once refined, rare earths are bright silvery metals which possess unique magnetic, luminescent and electrochemical properties. These properties enable greater efficiency, improved performance, miniaturization, speed, durability, and thermal stability.
What are they used for?
Rare earths are found in a wide range of products.
