Contents on the CD Rom

  • Iridium is a hard, lustrous, platinum-like metal.
  • Iridium is the most corrosive resistant metal known.
  • Iridium is virtually insoluble in lead even at high temperatures, and use is often made of this fact in preliminary steps in chemical
  • Iridium is found uncombined in nature with platinum and other platinum group metals in alluvial deposits.
  • Iridium is one of the rarest elements in the Earth's crust. But it is more abundant in other parts of the universe. Iridium is found in meteorites.
  • Iridium usually occurs in combination with one or more other noble metals. Two common examples are osmiridium and iridosmine, combinations of iridium and osmium.
  • Solvent extraction is a well established technique in which an aqueous solution is contacted with an immiscible organic liquid
    containing an extractant specific for an element in the aqueous phase.
  • The separation of platinum, palladium and iridium relies upon a particular metal being sclectivcly extracted from the aqueous phase by an immiscible organic solvent in counter-current mixersettler boxes.
  • Iridium and the other platinum metals tend to occur together. A series of chemical reactions is used to separate one metal from the other. The other metals are then removed by other techniques.
  • Iridium can react with both types chelating extractants, those coordinating through oxygen and/or nitrogen atoms and those coordinating through sulphur atoms, but reaction occurs only when the solution is heated.
  • Iridium is used principally as a hardening agent for platinum.
  • It is the most corrosion-resistant material known, and was used in making the standard metre bar, which is an alloy of 90% platinum
    and 10% iridium.
  • Platinum-iridium alloys are used to make crucibles and other high temperature equipment.
  • A major use for iridium is crucibles for producing large, pure, defect-free man-made crystals for electronic and industrial applications.
  • Used as a source of radioactivity (Ir-192) for the treatment of cancer.
  • Iridium is used as a catalyst for carbonylation of methanol to produce acetic acid .
