Description

Iridium is a rare metal that falls under the platinum elements in the Periodic Table. Its unique characteristics include a high 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. Its silvery-white appearance and exceptional corrosion resistance make it a popular strengthening component in platinum alloys. It is also used in equipment designed for extreme heat conditions. Vacuum evaporation processes create particle and surface modification coatings, data storage devices, and fuel cells with iridium.
