General Information on Iridium Oxide Coated Titanium Electrode Plates

Iridium tantalum oxide coated are considered the optimum choice as anodes in various industries for their strong corrosion resistance in acid environments, low overpotential for oxygen evolution, great physical stability, and environmental safety. Compared with traditional electrodes, Ir-Ta MMO electrodes present better electrochemical stability under a sulfate/chloride environment and longer service life.

Accumulated decades of coated titanium electrode technology, JAU kept providing our clients with high-quality Ir-Ta MMO electrodes regarding multiple oxygen-evolution systems. JAU electrodes have been applied to industries like copper foil production, electroplating, cathodic protection, organic synthesis, acid solution electrolysis, electrowinning, etc.
