Iridium

Description:

Iridium is a dense, silvery-white transition metal belonging to the platinum group of elements, known for its remarkable resistance to corrosion and oxidation. It has a high melting point and is one of the most corrosion-resistant metals, making it valuable in various industrial applications. Iridium is typically found in nature as an alloy with other platinum group metals and is often extracted from nickel and copper ores. Its atomic number is 77, and it exhibits a variety of oxidation states, with +3 and +4 being the most common in compounds. Iridium is used in high-temperature applications, electrical contacts, and spark plugs, as well as in the production of certain types of catalysts. Additionally, due to its rarity and unique properties, iridium is also utilized in specialized scientific instruments and in the field of jewelry. Its high density and hardness contribute to its durability, while its chemical inertness makes it suitable for use in harsh environments.
