What are Electrodes?

Electrodes are conductive materials used to establish electrical contact with a non-metallic part of a circuit. They are essential in electrochemical cells where they facilitate the transfer of electrons across the cell. In industries like chlor-alkali, electrodes coated with iridium are critical for the efficient production of chlorine and caustic soda through electrolysis.

Recovering Iridium from Electrodes

Auris Noble specializes in the recovery of iridium from spent electrodes used in various industrial processes. Our proprietary extraction process begins with the dismantling of the electrodes to separate the iridium-bearing layers. The iridium is then chemically processed to remove contaminants and refine the metal to a high degree of purity.

Applications of Refined Iridium

Refined iridium is extremely valuable in manufacturing new electrodes, particularly for the chlor-alkali industry, due to its resistance to corrosion and high electrical efficiency. It is also used in making crucibles for high-temperature material processing. Furthermore, refined iridium serves as a powerful catalyst in the chemical industry, catalyzing reactions such as the Haber process for ammonia synthesis and in pharmaceutical applications for drug development.

Iridium as Catalysts in Industries

In the chemical industry, iridium catalysts are crucial for achieving high efficiency and selectivity in reactions, making processes more environmentally friendly and cost-effective. Pharmaceutical manufacturers utilize iridium catalysts to synthesize complex molecules, enhancing the efficacy and safety of medications. These catalysts are indispensable in research and development, leading to innovations in sustainable chemistry and new medical treatments.
