High purity iridium powder is extracted as a by-product of nickel ores and a co-product of platinum metal. Among the most dense of all elemental metals, iridium is extremely stable and corrosion resistant. Its main application is in crucibles used to grow single crystal sapphire substrates for the electronics industry, but iridium is also used as an alloying along with gold and other platinum group metals.
SMI Ltd. stocks and supplies 99.9% iridium powder for use in the alloy and chemical industries. Please do not hesitate to contact us with your detailed requirements or for a current iridium price.
