One of the rarest and most precious metals on Earth, iridium is a lustrous, silvery-white transition metal that belongs to the platinum group of metals. It has a high resistance to corrosion and is known for its hardness and high melting point.
Named after the Greek goddess Iris, personification of the rainbow, iridium is commonly found in meteorites and in the Earth's crust, usually in combination with other platinum group metals. It is often extracted as a byproduct of nickel mining.
Properties of Iridium
Iridium is one of the densest and most corrosion-resistant elements, making it highly valuable in various industrial applications. It is used in spark plugs, electrical contacts, fountain pen nibs, and crucibles for growing large, high-purity single crystals.
Applications of Iridium
Due to its resistance to high temperatures and harsh chemicals, iridium is extensively used in the production of specialized equipment like crucibles, electrodes, and spark plugs. It is also used in the manufacture of mirrors for telescopes and X-ray detectors.
Furthermore, iridium plays a crucial role in the field of medicine, where it is used in radiation therapy to treat certain types of cancer. Its radioactive isotope, iridium-192, is commonly used in brachytherapy to deliver localized radiation treatment.
Conclusion
In conclusion, iridium is a remarkable metal with unique properties that make it indispensable in various industries, from electronics to medicine. Its rarity and high cost underscore its importance as a valuable and versatile element in our modern world.
