IR0887 Iridium Crucibles

Iridium Crucibles Description

Iridium is a platinum group metal with atomic number 77. Iridium is a very hard and brittle metal with silvery color. SAM's Iridium Crucibles are made from raw Iridium material with high purity & no defect by using the Plasma Double Melting process. Our hot forging machine and rolling mills enable us to produce high-density iridium plate good for making crucibles. Our iridium crucibles are used to grow various metal oxide single crystals, including scintillation crystals used in metal scanners and mobile phones as well as those used in liquid crystal display backlighting.

Typical Chemical Analysis

Iridium Crucibles Applications

Iridium Crucibles are mainly used for a particular way of single crystal growth, called the Czochralski method (CZ method). The remarkable characteristics of Iridium are 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 crystals 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.

Iridium Crucible Packaging

Our Iridium Crucibles are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
