![]() Due to its rarity and unique properties, iridium has become a symbol of prestige and luxury. It is one of the rarest elements on earth, making up only 0.001 ppm (parts per million) of the earth's crust. Iridium is a highly sought-after precious metal that has been used in various applications, from jewelry to electronics. Whether you are interested in jewelry, electronics, or science, there is something to appreciate about this rare and beautiful element. This has led some scientists to suggest that a meteorite impact may have been responsible for the extinction event.Īs you can see, iridium is a fascinating and valuable metal that has a wide range of applications. In 1980, a layer of iridium was discovered in the geological record that coincided with the extinction of the dinosaurs. Iridium is a very rare metal, and is only found in small quantities in the Earth's crust. Its name comes from the Greek word "iris", meaning rainbow, due to the fact that it has a number of colorful salts. Iridium was discovered in 1803 by British chemist Smithson Tennant. Iridium is also used in the aerospace industry, due to its high melting point and resistance to corrosion. It is used as a catalyst in the production of fertilizers, and in the refining of crude oil. Iridium is also used in electronics, particularly in the production of hard disk drives and other data storage devices. It is often used to make engagement rings, wedding bands, and other luxury items. One of the primary uses of iridium is in high-end jewelry. Iridium is also one of the densest elements, with a density of 22.56 g/cm. It has a melting point of 2,467C and a boiling point of 4,427C, making it one of the most heat-resistant metals in existence. Iridium is the most corrosion-resistant metal known, and is often alloyed with other metals to increase their resistance to wear and corrosion. It is a very hard, brittle, and dense metal that is difficult to work with. Iridium is a chemical element with the symbol Ir and atomic number 77. In this section, we will take a closer look at iridium, exploring its properties, uses, and history. But iridium is not just a pretty face it also has a number of practical applications. ![]() ![]() It has a beautiful silvery-white color, and is often used in high-end jewelry and electronics. With a density that surpasses that of both gold and platinum, iridium is considered one of the most valuable metals in the world. However, there is another metal that is even more rare and prestigious: iridium. When it comes to precious metals, gold and silver are often the first that come to mind.
