Uses
Uses & Benefits
  • 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.
  
  • It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
