설명

일반 설명

Iridium is a rare and dense transition metal that belongs to the platinum group of metals and is known for its remarkable physical and chemical properties. Iridium is used in high-temperature applications such as crucibles for crystal growth and in devices that operate under extreme conditions due to its high melting point and stability at elevated temperatures. It is also used in electrical contacts and electrodes because of its excellent corrosion resistance and electrical conductivity. In addition, iridium is used as a catalyst in various organic reactions including hydrogenation, water splitting, C-C coupling, and olefin metathesis.
