What is Palladium?
- Palladium(Pd), the chemical element with an atomic number of 46, is a rare element and has a lustrous silver appearance.
- Discovered by William Hyde Wollaston in the year 1803.
- The metal was named after the asteroid Pallas of the Greek goddess Athena.
Uses of Palladium
- The metal serves as a catalyst in many chemical processes like hydrogenation, petroleum cracking, and dehydrogenation.
- Palladium is a Lindlar catalyst and is sometimes referred to as Lindlar Palladium.
- Used in electrodes and also being a major component for multi-layer ceramic capacitors.
- Being an absorbent of hydrogen, used for storage of the same.
- Used for jewellery making since time immemorial.
- Used by photographers in making fine art with black and white prints using palladium salts.
Properties of Palladium
- The metal is highly resistant to corrosion in the air and some acids at room temperatures.
- It will dissolve in aqua regia and can be attacked by hot acids.
- It can form several salts and also form different compounds.
- A special feature of Palladium is that it absorbs hydrogen to a great extent (nearly 900 times its own volume).
Certain Facts About Palladium
- The metal has an incredible capacity to absorb hydrogen 900 times more than any other metal.
- Despite the metal being biologically inactive, it triggers allergies among certain people.
- Palladium is a fairly non-toxic metal.
