Uses & Benefits
- Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
-
It is also used as a catalyst in ethene polymerisation.
- 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.
