Iridium Crucibles Applications:

Iridium crucibles are mainly used for a particular way of single crystal growth, called Czochralski method (CZ method).. The remarkable characteristics of Iridium is high melting point up to more than 2,400 degrees C and high corrosion resistivity not to be dissolved even by nitro hydrochloric acid under normal temperature, and those are the reasons why Iridium is necessary for growing crystal of high melting point. CZ method is the way of crystal growth by touching seed crystal to melted raw materials of the crystal in the crucible, and then rotating and pulling up very slowly. LT (Lithium Tantalite) for noise filter of cell phone and Sapphire for LED substrate are representative crystals made with Iridium Crucibles.
