Platinum-iridium alloys (5 to 10 percent iridium) are readily workable metals that are much harder and stiffer and more resistant to chemical attack than the soft pure platinum. Iridium is chiefly used in the form of platinum alloys. It can be dissolved in concentrated hydrochloric acid in the presence of sodium perchlorate at 125° to 150° C (257° to 302° F).īecause of difficulties in preparation and fabrication, the pure metal has few applications. In the massive state the metal is practically insoluble in acids and is not attacked even by aqua regia. Abstract This paper examines processes for the preparation of metallic iridium nanoparticles under hydrothermal conditions. It is one of the densest terrestrial substances. A precious, silver-white metal, iridium is hard and brittle, but it becomes ductile and can be worked at a white heat, from 1,200° to 1,500° C (2,200° to 2,700° F). sunroof e85 flexfuel capable rear axle iridium metallic jet black audio system engine transmission. It is very dense and rare and is used in platinum alloys. Iridium (Ir), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table.
