4 Uses
4.1 Uses & Benefits
- Plutonium was used in atomic bombs and still it is being used in various weapons and Ammunition industry.
-
It is also used in nuclear power plant as source of energy for space missions.
- It has no commercial uses, but its alloys are in high demand. Lanthanum and Nickel alloy is used for the hydrogen gas storage.
- The best-known use for mischmetal alloy of Lanthanum is; as a ‘flints’ for cigarette lighters.
