- Palladium alloys are used for Jewelry contains (95% Palladium and 5% Ruthenium)
- In the late 1800s, Palladium metal used have more economical value than the Platinum metal.
- Palladium element is known as a good catalyst
- 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
- Mostly palladium metal is used in catalytic converters. In electronic industry it is used in ceramic capacitors of mobile and computer.
- It is used in jewellery and dental fillings and crowns.
- 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.
