Application

Iridium(III) chloride hydrate serves as a versatile compound primarily used for synthesizing various iridium-based materials, including Vaska's complex, trans-[IrCl(CO)(PPh3)2]. It plays a crucial role as a catalyst for oxidation processes in the presence of cerium(IV) and is integral to electrode manufacturing. This compound is essential in the field of iridium electroplating and contributes to the production of items like the standard meter bar of Paris and crucibles. Moreover, it is valuable for high-temperature electrical contacts, acts as a hardening agent, and is used in tipping pens, compass bearings, and Pt/Ir spark plugs. Additionally, it finds application in medical and surgical fields, in MMO titanium electrode coatings, and serves as a precursor in the development of heterogeneous catalysts.
