Product Name:Iridium
English Name:Iridium
CAS No.:7439-88-5
Aliases:Iridium powder, Sponge iridium
Molecular Formula:Ir
Physical Properties:Silver-white metal, hard and brittle, with an extremely high melting point and chemical inertness; insoluble in acids except aqua regia. Density 22.56 g/cm³ (20°C), melting point 2447°C, boiling point 4428°C. Maintains excellent oxidation and corrosion resistance even at elevated temperatures.
Uses:Primarily used for manufacturing high-purity iridium crucibles for high-temperature single-crystal growth and precision high-temperature containers. In the electrical industry, it is used for spark plug electrodes and high-temperature thermocouples. Due to its high hardness and corrosion resistance, it is also applied in critical aerospace engine components and heat-resistant alloys, such as platinum-iridium alloys for catalytic industrial applications.
Technical Specifications:
Purity: 99.95% (as Ir)
Molecular weight: 192.22
Melting point: 2447°C
Density: 22.56 g/cm³ (20°C)
Appearance: silver-white lump or powder
