Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, fragile, and a white transition metal, white, and platinum from the platinum group. Iridium is the second most dense metal with a density of 22.56 g / cm3 as defined by experimental X-ray crystallography. At room temperature and standard atmospheric pressure, iridium has a density of 22.65 g / cm3, 0.04 g / cm3 higher than measured osmium in the same way. It is the most corrosion-resistant metal, even at temperatures up to 2000 ° C. Although only some molten and halogen salts are corrosive to solid iridium, the finely divided iridium powder is much more reactive and can be flammable.
