Description:
The primary use of iridium is as a hardening agent in platinum alloys.Phenytoin Other uses are for the making of crucibles and devices that require high temperatures.Omaveloxolone Osmium/iridium alloys are used for compass bearings.PMID:36628218 Iridium is commonly used in complexes like Ir(mppy)3 and other complexes in polymer LED technology to increase the efficiency from 25% to about 100% due to triplet harvesting. Used in high-dose radiation therapy for the treatment of prostate and other forms of cancer. Iridium is used in tips of ballpoint pens. Iridium is used as a catalyst for carbonylation of methanol to create acetic acid. At one time, iridium as an alloy with platinum, was used in bushing the vents of heavy ordnance and, in a finely powdered condition (iridium black) for painting porcelain black.
