BLACK POWDER | [Uses]
Iridium(IV) oxide is used in the coating of anode-electrodes for industrial electrolysis in association with other rare oxides. It is also used in microelectrodes for electrophysiology research. | [Synthesis]
The iridium powder is obtained by heating to 107°C in air or oxygen, or by careful addition of a strong base to a boiling (IrCl6)2-solution, which produces a blue precipitate, the latter being dried in a vacuum, and then its hydrate is allowed to dehydrat |
