Palladium is mainly used as a catalyst in the chemical industry. However, this metal also has other applications. Palladium has superb corrosion resistance, and it is used in dentistry for tooth crowns. The presence of ruthenium or rhodium hardens palladium, resulting in applications such as a decolorizing agent of gold – the so-called "white gold" in jewellery.

Did you know?
  • Palladium is so malleable that it can be flattened into a leaf as thin as 1/250000 of an inch.

Palladium has no biological role, and all of its compounds should be considered highly toxic and carcinogenic. Interestingly, palladium chloride was once prescribed as a treatment for tuberculosis without too many side effects observed.
