FAQ

Frequently Asked Questions

As a solid metal, it is relatively stable, but its dust or powder can be a fire hazard and toxic if ingested or inhaled.

No, it is never found as a native metal. It always occurs in minerals mixed with other rare-earth elements and must be chemically extracted and reduced to its metallic form.

Its primary use is in manufacturing green phosphors for cathode ray tubes, LEDs, and fluorescent lamps. It is also used in Terfenol-D, a magnetostrictive alloy.

It is difficult and energy-intensive to separate from other very similar rare-earth elements, and global production volumes are very low, leading to high cost.
