Elemental Tile

Iridium

Iridium is a very hard, brittle, silvery-white transition metal and is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Although only certain molten salts and halogens are corrosive to solid iridium, finely divided iridium dust is much more reactive and can be flammable.

1803 by Smithson Tennant, Antoine Fourcroy, Louis Vanquelin and Hippolyte Collet-Descotils, England.
