Description of Iridium

IridiumIridium is a chemical element originated from Iris, the Greek goddess of the rainbow. It was first mentioned in 1803 and observed by S. Tennant. The isolation was later accomplished and announced by S. Tennant. “Ir” is the canonical chemical symbol of iridium. Its atomic number in the periodic table of elements is 77 with location at Period 6 and Group 9, belonging to the d-block. The relative atomic mass of iridium is 192.217(3) Dalton, the number in the brackets indicating the uncertainty.

Iridium is a rare, hard, lustrous, brittle, very dense platinum-like metal. Chemically it is almost as unreactive as gold. It is the most corrosion-resistant metal known and it resists attack by any acid. Iridium is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser.

Application of Iridium

– A hardening agent for special alloy
– Alloyed with osmium, which is used for bearing compass and tipping pens.
– Iridium crucibles.
– Iridium film, which is used as a protective film or heavy-duty electrical contacts.
– The international standard kilogram, which is an alloy of 90% platinum and 10% iridium.


Our iridium sputtering targets are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.

Love buying from Stanford Advanced Materials.. They always carried many options for coating materials.

The film made by high purity iridium sputter target is super hard. Meet my need.
