Platinum group metals (PGMs) are a group of six chemical elements that share similar properties and are often found together in nature. These elements are known for their rarity, high melting points, and exceptional resistance to corrosion and wear. The six platinum group metals are:
(Pt): Platinum is a dense, silvery-white metal with a high melting point. It is highly resistant to corrosion and is often used in jewelry, catalytic converters, and the chemical industry.
(Pd): Palladium is a silvery-white metal with properties similar to platinum. It is used in a wide range of applications, including catalytic converters, electronics, and dentistry.
Rhodium (Rh): Rhodium is a rare, silvery-white metal known for its high reflectivity and corrosion resistance. It is used for plating jewelry and as a catalyst in various chemical reactions.
Ruthenium (Ru): Ruthenium is a hard, white metal with excellent resistance to corrosion. It is used in electrical contacts, electronics, and catalysts.
Iridium (Ir): Iridium is one of the densest elements and is highly corrosion-resistant. It is used in electrical contacts, spark plugs, and some scientific instruments.
Osmium (Os): Osmium is the densest naturally occurring element and has a bluish-gray color. It is used in electrical contacts and is sometimes alloyed with other metals.
PGMs are often found together in nature, particularly in ores containing platinum and palladium. These metals have unique properties that make them valuable in various industries, including automotive (catalytic converters), electronics, jewelry, and the chemical and petroleum industries. Their rarity and specialized properties contribute to their high market value.
