Английская Википедия:Iridium(IV) oxide
Шаблон:Chembox Iridium(IV) oxide, IrO2, is the only well-characterised oxide of iridium. It is a blue-black solid. The compound adopts the TiO2 rutile structure, featuring six coordinate iridium and three coordinate oxygen.[1]
It is used with other rare oxides in the coating of anode-electrodes for industrial electrolysis and in microelectrodes for electrophysiology research.[2]
As described by its discoverers, it can be formed by treating the green form of iridium trichloride with oxygen at high temperatures:
- 2 IrCl3 + 2 O2 → 2 IrO2 + 3 Cl2
A hydrated form is also known.[3]
Application
Iridium dioxide can be used as an anode electrode for industrial electrolysis and as a microelectrode for electrophysiological studies.[4]
Iridium dioxide can be used to make coated electrodes.[5]
