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.
  
  • As this metal does not absorb neutrons; It is used in nuclear power stations.
  • Its oxide is used in ultra strong ceramics. It is also used in manufacturing Crucibles.
