3 Uses
3.1 Uses & Benefits
  • In some nuclear reactors sodium is used as a heat exchanger.
  • Compound of Sodium metals called Salt (Sodium chloride) is used in Food.
  • 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.
