Palladium is applied in the electrical industry in the production of electromechanical contacts as relays. In the chemical and pharmaceutical industry it is used as a catalyst of hydrogenation reactions and in the oil industry palladium is very important in the catalysis distilled petroleum fractions. The element is also applied in some alloys used in dental medicine. In jewelry palladium is hardened with a small fraction of ruthenium or rhodium, and can be used as decolorizing agent of gold, creating the so-called white gold.
