Electrochemical synthesis of an iridium powder with a large specific surface area

The synthesis of iridium powder in a molten NaCl–KCl medium at 700°C is carried out for the first time. The influence of the ratio of the cathode to the anode current density ( i c / i a ) on the structure and the morphology of the iridium powder is investigated. Single-phase and polycrystalline iri...

Zusammenfassung:The synthesis of iridium powder in a molten NaCl–KCl medium at 700°C is carried out for the first time. The influence of the ratio of the cathode to the anode current density ( i c / i a ) on the structure and the morphology of the iridium powder is investigated. Single-phase and polycrystalline iridium powders with a specific surface of 16.8 m 2 /g are produced. The phase composition and the surface texture of the deposits are studied. The specific surface and the particle size of iridium powders as functions of the ratio i c / i a are analyzed.
