- Erbium is a chemical radioactive element present as the eleventh element in the lanthanide series of the periodic table. The pure form of the element is a metal.
- Naturally, occurring Erbium is found in chemical combination with other naturally occurring elements. When it is artificially isolated its appearance is a silvery-white solid metal.
- It is metal used to color lenses of glasses.
- They are used as control rods in a nuclear reactor.
- It has a vital application in metal alloys.
- Erbium ion’s unique wavelength aids laser surgery.
- The pure form of Erbium metal is malleable.
- They are very stable and they do not oxidize quickly when exposed to air when compared to other rare earth metals.
- It comprises of properties that are similar to other rare earth materials or lanthanides.
- It is an interesting probe for a large variety of physical effects due to its unique properties.
