Iridium
(Ir) |
|
Iridium,
a precious metal, has an appearance similar to platinum in that it is
white but with a slightly yellowish tint. Iridium, the most
corrosion-resistant metal known, is very hard, brittle, and has a low
ductility, making it difficult to machine, form, or work.s.
Iridium
is the most corrosion resistant metal known. It is completely unattacked
by the common mineral acids at normal and high temperatures, and
by cold and boiling aquaregia. It is the most resistant of the platinum
metals to the halogens. It is slightly attacked by fused sodium and
potassium hydroxides and by fused sodium bicarbonate. Iridium is resistant
to anodic corrosion in aqueous electrolytes, but may be attacked
in aqueous potassium cyanide, hydrochloric acid, and ammonium carbonate
solutions under the action of an alternating current.
