Iridium is a hard, brittle, lustrous, silvery-white, dense metal that belongs to the platinum group. It exhibits the highest corrosion resistance among metals. Scientists primarily use pure iridium as a hardening agent for platinum. Researchers use iridium crucibles to produce single crystals for subsequent experimental analysis. Engineers use iridium for coating electrodes in the chlor-alkali process and in catalyst formulations.

Iridium is a hard, brittle, lustrous, silvery-white, dense metal from the platinum group. It is the most corrosion‐resistant metal. Pure iridium is generally used as a hardening agent for platinum. Iridium crucibles are typically employed for growing large, high-purity single crystals. Today, iridium is used for coating electrodes in the chlor–alkali process and in catalysts.
Iridium is a hard, silvery metal. It is nearly as unreactive as gold. It has a high density and an elevated melting point. Iridium is the most corrosion-resistant material known. It is utilised in specialised alloys and forms an alloy with osmium, which is used for pen nibs and compass bearings. It was used in the production of the standard metre bar, which consisted of an alloy of 90 % platinum and 10 % iridium. Owing to its high melting point and low reactivity, it is also used for contacts in spark plugs.
Stanford Advanced Materials (SAM) can now offer various iridium products, including:
Rare and resistant: Iridium is one of the rarest elements in the Earth's crust, with an estimated abundance of approximately 0.001 parts per million. Its density measures around 22.56 g/cm³ and its corrosion resistance remains high under severe conditions. Consequently, it is used in specific industrial applications.
High melting point: Iridium has a melting point of approximately 2446 °C. This property permits its use in processes that operate at elevated temperatures.
Catalytic performance: Iridium exhibits catalytic activity in petroleum refining. It increases reaction efficiency when used to facilitate chemical reactions.
Electrochemical applications: The chemical stability of iridium and its electrochemical properties make it suitable for use in electrodes for fuel cells and medical implants.
Aerospace and exploration: Iridium’s durability and temperature tolerance allow its use in satellite propulsion systems and components for aerospace applications.
