Palladium Platinum and Rhodium

Palladium and Platinum are silvery colored precious metals, many times rarer than Gold, that have very unique chemical properties that make them of significant importance for industrial purposes. Specifically they are "catalysts" which means they encourage chemical reactions by their mere presence. Many people do not realize that Palladium is used in automotive catalytic converters more than Platinum.

Both metals are used for jewelery and as precious metals investing.
