2 Facts
2.1 Interesting Facts
- Naturally occurring minor elements include Cadmium.
- Cadmium is released into atmosphere to control volcanic eruption and forest fires.
- It is used for electroplating of Steel for corrosion resistance.
- It can absorb neutrons and used in nuclear reactor to control atomic fission.
- Metal dust of Lutetium element is highly explosive.
- Lutetium metal is corrosion resistance and acts stable in air.

3 Uses
3.1 Uses & Benefits
- It has very limited uses as it is a toxic metal and it can cause birth defects, cancer, etc.
-
Almost 80% of Cadmium metal is used in Nickel cadmium Batteries and now it is getting replaced with nickel hydride.
- Lutetium metal is used outside research. It has commercial uses like Industrial catalyst for cracking oil refineries of hydrocarbons .
