Uses
Uses & Benefits
  • Currently known uses of Flerovium metal are limited to research purpose only.
  
  • Polonium metal has different Allotropes, it is used in antistatic devices and for research purpose.
  • A 1 gram of Polonium can reach a temperature of 500°C, hence it is used as a heat source for space equipment.
