Made in 1889, the International Prototype Metre is made of an alloy containing 90 percent platinum and 10 percent iridium and is kept by the international bureau of weights and measures near Paris. The radioisotope iridium-192 is an important energy source in γ radiography, which helps in the non-destructive testing of metals. In addition, brachytherapy uses the gamma rays released by Ir to treat cancer. This treatment method places the radiation source near or inside the cancer tissue and can be used to treat prostate cancer, cholangiocarcinoma, and cervical cancer.
In this process, iridium compounds can be used as catalysts. Iridium is also often used in instruments that must withstand high temperatures. Iridium alloy can resist arc erosion, so it is an ideal material for spark plug electrical contacts. Cativa catalytic method is the process of converting methanol into acetic acid. Pure platinum has a Vickers hardness of 56 HV, while platinum alloys containing 50 percent iridium can exceed 500 HV. Iridium has strong corrosion resistance and high-temperature resistance, so it is very suitable as an alloy additive. Some long-term components in aircraft engines are made of iridium alloy, and the iridium-titanium alloy is also used as a material for underwater pipes. The addition of iridium increases the hardness of the platinum alloy.
The application of iridium mostly uses its high melting point, high hardness, and corrosion resistance. Iridium metal, along with iridium-platinum alloy and osmium-iridium alloy, has a very low loss and can be used to manufacture porous spinnerets. Spinnerets are used to extrude plastic polymers into fibers, such as rayon. Osmium-iridium alloys can also be used for compass bearings and weight scales.
