Uses & Benefits
- Its alloys are used in spacecraft, aircraft and ammunition industry.
- Its pipes are used in distillation plants, submarines, hulls of big ships, etc.
- 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.
