Palladium is also used in jewelry, dentistry, [41] [42] watch making, blood sugar test strips, aircraft spark plugs, surgical instruments, and electrical contacts. [43] Palladium is also used to make some professional transverse (concert or classical) flutes. [44] As a commodity, palladium bullion has ISO currency codes of XPD and 964.
In Greek and Roman mythology, the Palladium or Palladion (Greek Παλλάδιον (Palladion), Latin Palladium) [1] was a cult image of great antiquity on which the safety of Troy and later Rome was said to depend, the wooden statue of Pallas Athena that Odysseus and Diomedes stole from the citadel of Troy and which was later taken to the ...
Palladium(II) acetate, Pd(OAc) 2. Most ionic compounds of palladium involve the Pd 2+ oxidation state. Palladium(II) chloride is a starting point in the synthesis of other palladium compounds and complexes. [1] Palladium(II) acetate plus triphenylphosphine is used as a catalyst in organic synthesis.

Gold nugget A selection of precious metal elements; gold, silver, platinum, palladium, copper, ruthenium, rhodium, rhenium, osmium, iridium and mercury. They are labeled and arranged by their location on the periodic table. Precious metals are rare, naturally occurring metallic chemical elements of high economic value.
This article summarizes the world palladium production by country. This is a list of countries by palladium production in kilograms, based upon data from the United States Geological Survey. [1] In 2019, the world production of palladium totaled 210,000 kilograms—down 5% from 220,000 kg in 2018.
Naturally occurring platinum and platinum-rich alloys were known by pre-Columbian Americans for many years. [5] However, even though the metal was used by pre-Columbian peoples, the first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger (1484–1558) as a description of a mysterious metal found in Central American mines between ...
Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. The unique properties of palladium and other platinum group metals account for their widespread use.
Organopalladium chemistry is a branch of organometallic chemistry that deals with organic palladium compounds and their reactions. Palladium is often used as a catalyst in the reduction of alkenes and alkynes with hydrogen. This process involves the formation of a palladium-carbon covalent bond.
