Interesting Facts
- Luster of Indium is bright in nature.
- Reich and richer were looking for thallium in zinc metal and they discovered Indium metal.
- 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
- It is used to produce indium tin oxide (ITO), it is used in manufacturing touch screens, flat screen TVs and solar panels.
- Its nitride, phosphide and antimonide are used in transistors and microchips.
- 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.
