Palladium is similar to other elements of the platinum group, it is a silver metal that is relatively non-reactive, but of the group has the lowest melting point and is the least dense. In its applications it is more similar to platinum: useful in the metallic form for the production of a variety of products and as a catalyst.
Palladium catalyzes reactions involved in oil breakdown, water treatment, nitric acid production and polymer fabrication, and is found in catalytic converters and fuel cells as a catalyst.
It is also used to increase the rate of hydrogenation and dehydrogenation reactions, and serves many catalytic functions specialized in organic chemistry.
