Uses

Uses & Benefits
  • Currently known uses of Livermorium metal are limited to research purpose only.
  
  • It has an ability to absorb neutrons and hence it is used to make control rods in nuclear submarines. And this metal is also used in Plasma welding torches.
  • It alloys with iron, titanium and niobium are very useful.
