Uses

Uses & Benefits
  • 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.
  
  • It has a tendency to get tarnished in the open air, but when alloyed with elements like erbium, vanadium, its hardness levels decreases.
  • Its compounds like Erbium oxide is used in safety glasses of welders and metal workers.
