Iridium is a chemical element with symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, iridium is generally credited with being the second densest element (after osmium). It is also the most corrosion-resistant metal, even at temperatures as high as 2000 ¡ãC. Although only certain molten salts and halogens are corrosive to solid iridium, finely divided iridium dust is much more reactive and can be flammable

Material Notes

Iridium Sputtering Targets, Purity is 99.9%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm. Bonding is recommended for these materials. Many materials have characteristics which are not amenable to sputtering, such as, brittleness and low thermal conductivity.This material may require special ramp up and ramp down procedures. This process may not be necessary with other materials. Targets that have a low thermal conductivity are susceptible to thermal shock.
