The platinum group elements (PGEs) consist of six metallic elements: platinum, palladium, rhodium, iridium, osmium, and ruthenium. These elements are known for their high resistance to corrosion, excellent catalytic properties, and high melting points. They are often found together in nature and are primarily sourced from mineral deposits. PGEs are widely used in various industries, including automotive, electronics, and jewelry. For example, catalytic converters in vehicles utilize palladium and rhodium to reduce harmful emissions. Their unique properties make them valuable for applications in chemical reactions and as catalysts in industrial processes.
