Uses & Benefits
- 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.
- Ytterbium metal is used in memory devices and tuneable laser.
-
It is also used as industrial catalyst as the other catalysts are too toxic and polluting.
