Characteristic
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.
Chemical formula:IrO2
Molar mass: 224.22 g/mol
Appearance: blue-black solid
Density: 11.66 g/cm3
Melting point: 1,100 °C (2,010 °F; 1,370 K) decomposes
Solubility in water:insoluble
Magnetic susceptibility (χ):+224.0·10−6 cm3/mol
Crystal structure:Rutile (tetragonal)
Applicatio
It is used with other rare oxides in the coating of anode-electrodes for industrial electrolysis and in microelectrodes for electrophysiology research.
