Iridium is a metallic chemical element with atomic number 77 and symbol Ir in the periodic table. It is a transition metal in the platinum group. Iridium is known to be one of the densest and hardest elements on Earth. It is found in platinum minerals and is often obtained as a byproduct of platinum ore processing.

Due to its rarity and unique properties, iridium is used in a variety of applications, including laboratory equipment, platinum resistance thermometers, electrical contacts, chemical catalysts, and high-end jewelry. However, its best-known application is in spark plugs for internal combustion engines, where its resistance to extreme heat and corrosion is highly valued.

Iridium is considered one of the most expensive materials in the world due to its rarity and the cost associated with its extraction and processing. At times, the price of iridium can surpass the price of gold, making it one of the most valuable metals in terms of cost per unit weight.

Origin of Iridium

Iridium, like many other heavy elements, has its origins in nuclear processes inside stars. During the life cycle of a star, especially during supernova explosions, elements heavier than iron are formed through nuclear fusion. Iridium is one such element that is created in such extreme conditions.

After these elements are formed in supernovae, they are dispersed into interstellar space. Some of this material can eventually aggregate and form new stars and solar systems, including our own. Therefore, elements such as iridium, which are not formed in the first generations of stars, are incorporated into planetary systems during the formation of these younger solar systems.

On Earth, iridium is found primarily in platinum mineral deposits. Metallic iridium is often mined as a byproduct of mining for platinum and other platinum group metals.

absurd cost

The cost of iridium is generally considered high due to its rarity and difficulty in extraction. Iridium is found in extremely low concentrations in the Earth's crust, which makes its extraction and purification an expensive process. In addition, the demand for iridium in various industries, such as the manufacture of spark plugs, laboratory equipment and chemical catalysts, also contributes to keeping its price high.

The cost of iridium can fluctuate over time, depending on factors such as supply and demand, mining conditions, and global economic stability. At times, the price of iridium can surpass the price of gold, making it one of the most expensive materials per unit weight.

However, despite its high cost, iridium continues to be valued for its unique properties, such as its resistance to corrosion and heat, making it essential for a variety of technological and industrial applications.
