Palladium definition, a rare metallic element of the platinum group, silver-white, ductile and malleable, harder and fusing more readily than platinum: used chiefly as a catalyst and in dental and other alloys. Symbol: Pd; atomic weight: 106.4; atomic number: 46; specific gravity: 12 at 20Â°C. See more.
Palladium: the essentials. Palladium is a steel-white metal, does not tarnish in air, and is the least dense and lowest melting of the platinum group metals. When annealed, it is soft and ductile. Cold working increases its strength and hardness.It is used in some watch springs.alladium is found as the free metal associated with platinum and other platinum group metals in Australia, Brazil, Russia, Ethiopia, and North and South America, as well as with nickel and copper deposits (from which it is recovered commercially) in Canada and South Africa.
