Iridium, a chemical element with the symbol Ir and atomic number 77, typically exhibits a silvery-white appearance. This platinum group metal presents a metallic luster, contributing to its perceived coloration. The term, derived from the Greek word for rainbow, refers to the variety of colors observed in its salts.
The metal’s resistance to corrosion, even at elevated temperatures, is a significant benefit, leading to its use in applications requiring durability and longevity. Historically, iridium has found applications in standard weights and measures, electrical contacts, and crucibles due to its robust properties. Its contribution to specialized applications is significant.
