Platinum Group of Metals
The platinum group metals, or PGM, are a collection of six heavy transition metals. They are platinum, palladium, rhodium, iridium, ruthenium and osmium. The platinum group metals typically occur together in the same mineral deposits
All the platinum group metals have excellent catalytic properties. They are extremely resistant to wear and tarnish as well as to chemical attack, have excellent high-temperature characteristics, and stable electrical properties. All these properties make the platinum group metals very useful for various industrial applications.
As a result of rapid technological advances, new uses for platinum group metals are still being discovered today.
