- 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
analysis.
- 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
