Uses & Benefits
- Silver is mainly used for Jewelry and show piece.
- It is used for manufacturing high quality mirrors due to its reflectivity property.
- Holmium metal has an ability to absorb neutrons, so this metal is used in nuclear reactors to keep the chain reactions of elements under control.
-
Alloys of Holmium are used to produce Magnet.
