Palladium is a lustrous silver-white metal. It has a face-centered cubic crystalline structure, at ordinary temperatures it is strongly resistant to corrosion in air and to the action of acids. Attacked by hot acids, and it dissolves in aqua regia. Forms many compounds and several complex salts. Has a great ability to absorb hydrogen (up to 900 times its own volume).
Low voltage electrical contacts. When it is finely divided, palladium forms a good catalyst and is used to speed up hydrogenation and dehydrogenation reactions.
Jewelry-making in certain alloys called “white gold.” It may be alloyed with platinum or substituted for it. It is used in watch bearings, springs, and balance wheels and also for mirrors in scientific instruments.
