| iridium | <chemistry, element> A rare metallic element, of the same group as platinum, which it much resembles, being silver-white, but harder, and brittle, and indifferent to most corrosive agents. With the exception of osmium, it is the heaviest substance known, its specific gravity being 22.4. Iridium usually occurs as a native alloy with osmium (iridosmine or osmiridium), which may occur alone or with platinum. Iridium, as an alloy with platinum, is used in bushing the vents of heavy ordnance. It is also used for the points of gold pens, and in a finely powdered condition (iridium black), for painting porcelain black. Atomic weight: 192.5 Abbreviation: Ir Origin: NL, fr. L. Iris, iridis, the rainbow. So called from the iridescence of some of its solutions. See Iris. (30 Mar 1998) |

| iridium |
Iridium is a chemical element in the periodic table that has the symbol Ir and atomic number 77. A heavy, very hard, brittle, silvery-white transition metal of the platinum family, iridium is used in high strength alloys that can withstand high temperatures and occurs in natural alloys with platinum or osmium. Iridium is notable for being the most corrosion resistant element known and for its association with the demise of the dinosaurs. ...
