4 Uses
4.1 Uses & Benefits
  • Currently known uses of Livermorium metal are limited to research purpose only.
  • 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.
