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.
- Holmium metal has an ability to absorb neutrons, so this metal is used in nuclear reactors to keep the chain reactions of elements under control.
-
Alloys of Holmium are used to produce Magnet.
