Mixed Metal Oxide (MMO) Anodes are advanced titanium-based electrodes designed for superior corrosion protection in Impressed Current Cathodic Protection (ICCP) systems. Their unique coating ensures long-lasting performance in challenging environments.
Request a QuoteMMO anodes are titanium substrates coated with a thin, electrochemically active layer of mixed metal oxides, typically containing Iridium and Ruthenium oxides. This coating provides excellent electrocatalytic properties, allowing the anode to efficiently discharge the protective current in an ICCP system with an extremely low consumption rate. This inert nature makes them the gold standard for long-term, high-current cathodic protection.
Titanium Substrate: Provides mechanical strength and excellent corrosion resistance in the passive state.
MMO Coating: The active layer (Iridium/Ruthenium Oxide) acts as a stable catalyst for the oxygen or chlorine evolution reaction, ensuring minimal wear and tear on the anode itself.
Extremely low consumption rate (typically less than 1 mg/A-year) ensures a service life of 20+ years, minimizing replacement costs.
Can operate at high current densities without passivation, making them ideal for high-resistivity or large-scale projects.
Available in various shapes (tubular, ribbon, wire, disc) to suit different installation environments (soil, water, concrete).
The coating is stable and non-toxic, posing minimal environmental risk compared to other anode materials.
We offer a comprehensive range of MMO anode configurations, each optimized for specific cathodic protection applications.
| Anode Type | Configuration | Primary Application |
|---|---|---|
