What is Erbium?
- 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 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.
Uses of Erbium
- This metal is used to colour the lenses of glasses.
- It is also used in the control rods of nuclear reactors.
- It has a vital application in the production of metal alloys.
- Erbium ion’s unique wavelength aids laser surgery.
Properties of Erbium
- The pure form of Erbium metal is malleable.
- It is very stable and it does not oxidize quickly when it is exposed to air (when compared to other rare earth metals).
- It comprises 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.
Certain Facts About Erbium
- Although Erbium is considered as a rare metal, it is actually not since it is the forty-fifth most abundant element found in the earth’s crust.
