MMO titanium anode
Superior conductivity for efficient electrochemical reactions.
Durable ruthenium coating enhances electrode lifespan.
Excellent stability in aggressive environments.
Customizable sizes for various industrial applications.
Product Introduction
An MMO titanium anode, also known as a mixed metal oxide titanium anode, is a type of electrochemical anode made from a titanium substrate coated with a thin layer of mixed metal oxides. The coating typically includes iridium oxide (IrO₂), ruthenium oxide (RuO₂), or tantalum oxide (Ta₂O₅). These oxides serve as the catalytic surface that drives electrochemical reactions efficiently, while the titanium base provides outstanding corrosion resistance and mechanical strength.
The MMO titanium anode has become a critical component across a range of industries, from water treatment and electroplating to cathodic protection and chlor-alkali production. Its unique structure ensures long service life, low electrical consumption, and stable performance even in highly corrosive environments.

Technical Features and Advantages of MMO Titanium Anodes
1. Exceptional Corrosion Resistance
The titanium base metal provides outstanding protection against corrosion in acidic, alkaline, and saline environments. The MMO coating further enhances this resistance, making the anode ideal for use in aggressive electrochemical processes.
2. High Electrical Efficiency
The MMO titanium anode exhibits low overpotential, ensuring reduced energy consumption during operation. This translates to significant cost savings and improved process efficiency over time.
3. Long Service Life
Compared to traditional graphite or lead-based anodes, MMO titanium anodes deliver much longer service life — often exceeding 10 to 20 years depending on the application and operating environment.
4. Environmentally Friendly
Unlike lead dioxide or mercury-based anodes, the MMO titanium anode does not release toxic substances into the environment. It supports cleaner, greener production processes that comply with global environmental standards.
5. Easy Maintenance and Reusability
After years of use, the titanium substrate can be re-coated, extending the anode’s life cycle and reducing replacement costs.
Applications of MMO Titanium Anodes in Various Industries
1. Cathodic Protection Systems
MMO titanium anodes are widely used in cathodic protection (CP) systems to prevent corrosion in steel structures such as pipelines, storage tanks, offshore platforms, and ship hulls. In these systems, the MMO anode serves as a long-lasting and stable source of impressed current, ensuring continuous protection in marine and underground environments.
2. Water Treatment and Electrolysis
In wastewater treatment and seawater desalination, MMO titanium anodes are used for electrolytic oxidation of organic pollutants, chlorine generation, and pH control. Their high oxygen evolution potential and corrosion resistance make them ideal for continuous water purification operations.
3. Electroplating and Metal Finishing
In electroplating, MMO titanium anodes replace traditional lead or graphite anodes. They maintain stable current distribution, improve plating quality, and reduce maintenance frequency. Common applications include electroplating of copper, nickel, chromium, and zinc.
4. Chlor-Alkali Industry
MMO titanium anodes play a crucial role in the chlor-alkali process, where they generate chlorine gas and sodium hydroxide through the electrolysis of brine. Their excellent chlorine evolution properties and low cell voltage contribute to high production efficiency.
5. Electrowinning and Electrorefining
In the mining industry, MMO titanium anodes are used for electrowinning of metals such as copper, nickel, cobalt, and zinc. Their stable electrochemical performance ensures high metal recovery rates and low maintenance costs.
6. Pool and Spa Disinfection Systems
For swimming pools and spa facilities, MMO titanium anodes are employed to produce chlorine or ozone through electrolysis, ensuring safe and clean water without the need for chemical additives.
Successful Applications of MMO Titanium Anodes Case:
1: Cathodic Protection for Offshore Platform
A major offshore oil company implemented MMO titanium anodes for its impressed current cathodic protection (ICCP) system. The anodes operated efficiently for over 15 years without any noticeable degradation, reducing maintenance costs and ensuring continuous corrosion protection.
2: Electrolytic Wastewater Treatment Plant
In an industrial wastewater treatment project, MMO titanium anodes replaced traditional graphite anodes. The plant achieved a 30% reduction in energy consumption and a 50% improvement in pollutant removal rate, demonstrating the superior electrochemical activity of MMO coatings.
3: Chlorine Generation for Water Disinfection
A municipal water facility adopted MMO titanium anodes to produce chlorine on-site for disinfection. The stable chlorine evolution performance eliminated the need for external chemical supply and enhanced operational safety.
