MMO Ru-Ir Coating Titanium Anode
The anode is the electrode where the oxidation reaction occurs. Titanium Expanded Metal Mesh Anode is manufactured using an expanded metal substrate coated with mixed metal oxide (MMO). The surface area of the mesh is 1.2x or more than that of the equivalent solid plate electrode.
Recommend the coating 0.05~3μm, If the thickness of the coating layer is less than 0.05 micrometers, the metal substrate is not sufficiently covered, and if the thickness is more than 3μm, the resistance will be increased.
- Demonstrated reliability
- Exceptionally long life
- Available in numerous anode configurations
- Lightweight
- Low cost

MMO Ru-Ir Coating Titanium Anode for Chlor-alkali Industry
The Expanded Metal Titanium Anode is a high-conductivity, corrosion-resistant anode specifically designed for electrolysis applications, particularly in the chlor-alkali industry. It is manufactured by coating a titanium substrate, such as a pure plate or expanded mesh, with a mixture of metal oxides, typically RuO₂, IrO₂, or PtO₂. This coating facilitates efficient electron transfer, catalyzes the electrochemical reactions, and ensures long-term durability even under highly oxidative conditions.
In the chlor-alkali process, sodium chloride (NaCl) brine is electrolyzed. Chloride ions are oxidized at the anode to produce chlorine gas, while hydrogen gas and caustic soda (NaOH) are generated at the cathode. Using our MMO-coated electrodes offers significant advantages over traditional graphite electrodes: lower loss, reduced chlorine evolution potential, excellent dimensional stability, and superior chlorine gas purity with lower energy consumption.
