Palladium is a shiny light grey color metal, which is highly resistive to corrosion. It received its name after an asteroid Pallas known as one of the largest in the Solar System. Palladium is non-toxic and had no big importance for living organisms. It is quite rare but can be found in its pure form on our planet. Generally, it is obtained from braggites or other minerals. It forms a number of compounds which are used in chemical industry and for researches. Applications of palladium are quite numerous: primarily, it is used as a catalyst, to speed up chemical reactions (especially in organic chemistry). Due to its excellent properties to absorb hydrogen, palladium can be used as hydrogen storage. It is also a part of alloys for producing dental amalgams, jewelry, in soldering and producing some electronic parts, etc.
