Interesting Facts
- Gadolinium is not found free in nature, hence it is not a native metal.
- Gadolinium metal found in minerals like Monazite and Bastnaesite.
- Cerium is a rare earth metal but still it is not rare at all.
- It’s non-toxic compound Cerium sulfide has a rich red color and it is used as a pigment.
- Cerium metal is also used in Flat screen TVs, light bulb, floodlights, etc.

Uses & Benefits
- Its alloys are also used in making Magnets, electronic components and Data storage devices.
- Compound of Gadolinium metal are used in magnetic resonance imaging (MRI).
- It is used to include flints for cigarette lighters.
- Its compound Cerium (Ill) Oxide is used as a catalyst; it is put inside the walls of the oven as it prevents from the buildup of cooking residues.
