Understanding MMO Anodes: Composition, Benefits, and Applications

What is Mmo anode ?

MMO anode stands for Mixed Metal Oxide anode. These anodes are used in various electrochemical applications, particularly in cathodic protection systems to prevent corrosion of metal structures such as pipelines, storage tanks, and marine vessels.

MMO anodes are composed of a titanium substrate coated with a mixed metal oxide catalyst. The coating typically includes a combination of precious metals like iridium, ruthenium, or platinum, which provide excellent electrochemical properties. The titanium substrate offers high mechanical strength and resistance to corrosion, while the mixed metal oxide coating ensures efficient and stable electrochemical performance.

Key advantages of MMO anodes include:

1. Durability: They have a long service life due to their resistance to corrosion and wear.
2. Efficiency: They provide a stable and efficient current output, which is crucial for effective cathodic protection.
3. Low Maintenance: They require minimal maintenance compared to other types of anodes.
4. Versatility: They can be used in a variety of environments, including seawater, freshwater, and soil.

MMO anodes are widely used in industries such as oil and gas, water treatment, and marine engineering due to their reliability and effectiveness
