Uses & Benefits
- It is mainly used for Galvanizing other metals.
- It is also used for manufacturing die-casting and it is very essential for automobile industry.
  
- 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.
