Palladium (Pd) is an element belonging to the platinum group of metals, palladium is steel-white in color, except in powder form, when it appears black. Palladium has the lowest melting point (2830.82 °F) and is the least dense of the PGMs. Deposits of palladium are rare, but are found in South Africa, Canada, and Russia. Much of the world's demand for palladium is met by recycling catalytic converters.
