Iridium tips improve the performance of automotive spark plugs to improve the efficiency of the combustion process in gasoline engines, again relying on high temperature stability, and linking to the opportunities and threats experienced by the other PGMs in the automotive market.Īlong with platinum, iridium is also used as a minor alloying component in some medical devices, notably guide wires and stents, by virtue of its biocompatibility and mechanical properties for micromachining complex tiny devices. This paperdescribes investigations carried out to determine the metal losses from polycrystalline iridium discs, by means of a. Some overcapacity has seen crucibles originally set for the LED industry repurposed for the SAW filter industry. Iridium reacts with oxygen at high temperatures forming volatile oxides, the evaporation of which considerably increases the iridium losses in oxygen-containing atmospheres, when compared with high-vacuum conditions. A very hard, brittle, silvery-white transition metal of the platinum group, it is considered the second-densest naturally occurring metal (after osmium) with a density of 22.56 g/cm (0.815 lb/cu in) as defined by experimental X-ray crystallography. In the electrical sector, iridium’s high temperature stability and purity have led to the use of iridium crucibles in growing materials for light emitting diodes (LED) for energy efficient lighting and, more recently, materials for surface acoustic wave (SAW) filters, devices found in increasing quantity in all smartphones and numerous other devices. Specializing in platinum group metals (PGMs) recovery, our focus is on returning value from our customers waste stream and increasing sustainability to the. Iridium is a chemical element with the symbol Ir and atomic number 77.
Iridium and ruthenium are used together in several industrial chemical processes, including the manufacture of acetic acid, a key intermediate in the manufacture of other bulk chemicals.īoth metals are used together in electrode coatings able to withstand the very harsh operating environment of a wide range of electrochemical processes, including the production of bulk chemical intermediates chlorine and sodium hydroxide.
