About Iridium (Ir)

Symbol: Ir
Atomic number: 77
Atomic weight: 192.217
Element category: transition metal
Iridium is a hard, brittle, lustrous, silvery-white, dense metal of the platinum group. It is also the most corrosion-resistant metal.
Pure iridium is generally used as a hardening agent for platinum. Iridium crucibles are commonly used for growing large high-quality single crystals. Now iridium is also often used to coat the electrodes in the chlor-alkali process and in catalyst.

Iridium is a hard, silvery metal. It is almost as unreactive as gold. It has a very high density and melting point. Iridium is the most corrosion-resistant material known. It is used in special alloys and forms an alloy with osmium, which is used for pen tips and compass bearings. It was used in making the standard metre bar, which is an alloy of 90% platinum and 10% iridium. It is also used for the contacts in spark plugs because of its high melting point and low reactivity.
