Description

Iridium, part of the rare platinum group elements, exhibits a melting point of 2,410°C, a density of 22.42 g/cc, and a vapor pressure of 10-4 Torr at 2,380°C. It showcases remarkable stability to air, water, and acids, including aqua regia, due to its location in the periodic table. This silvery-white metal boasts remarkable corrosion resistance. Primarily, it serves as a strengthening component for platinum alloys and features in high-temperature device applications. Moreover, iridium is utilized in vacuum evaporation to produce coatings for particle and surface modifications, data storage tools, and fuel cells.

Here are some important points about iridium:

Hardness and Durability: Iridium is one of the most corrosion-resistant metals, making it highly durable and suitable for harsh environments. It's exceptionally hard and brittle, with a high melting point.
Applications in Alloys: Iridium is commonly alloyed with other metals to improve their mechanical properties, especially in making hard and corrosion-resistant alloys used in pen tips, electrical contacts, and spark plugs.
Catalysts: Its catalytic properties find applications in chemical processes, especially in the chemical and petroleum industries.
Electrical Contacts: Iridium's resistance to corrosion and high temperatures make it valuable in electrical contacts and sparking devices.
Scientific and Medical Applications: Due to its high resistance to corrosion and radioactivity, iridium is used in some medical devices and scientific instruments. It's also utilized in some radiation therapy procedures.
Aerospace and Space Industry: Iridium's exceptional durability makes it valuable in aerospace components subjected to extreme conditions. Small amounts of iridium are also found in some meteorites, possibly indicating its presence in asteroids and other celestial bodies.
Jewelry: Iridium is occasionally used in jewelry, often as an alloy to harden and strengthen platinum.
Historical Significance: Iridium gained attention due to its role in the layer found in the Earth's crust, signifying the boundary between the Cretaceous and Paleogene periods, associated with the mass extinction of dinosaurs.
