Ru-Ir MMO Titanium Anode for Industrial Chlorine and Caustic Soda Production
The DSA Anode for Chlor-Alkali Process is a high-performance dimensionally stable anode (DSA) specifically engineered for industrial chlor-alkali applications. Manufactured using high-purity titanium substrate coated with ruthenium-iridium mixed metal oxide (Ru-Ir MMO), this anode offers exceptional chlorine evolution efficiency, low energy consumption, outstanding corrosion resistance, and long service life under highly aggressive brine electrolysis conditions.
The chlor-alkali industry relies on the electrolysis of sodium chloride solution to produce chlorine gas, hydrogen gas, and sodium hydroxide (caustic soda). As one of the most critical components within the electrolyzer, the anode directly affects production efficiency, operating costs, and plant reliability.
Compared with traditional graphite anodes, modern DSA anodes significantly improve electrolysis efficiency while reducing maintenance requirements and energy consumption.

What Is a DSA Anode for Chlor-Alkali Process?
DSA stands for Dimensionally Stable Anode.
A DSA anode consists of:
- Titanium substrate
- Mixed metal oxide catalytic coating
The titanium provides structural stability and corrosion resistance, while the MMO coating delivers excellent electrocatalytic performance.
Unlike graphite electrodes, DSA anodes maintain their geometry during operation and provide stable electrochemical performance over long operating periods.
Because of these advantages, DSA technology has become the industry standard for chlor-alkali production worldwide.
Why DSA Anodes Are Used in Chlor-Alkali Plants
The chlor-alkali process requires continuous operation in highly concentrated brine environments.
Traditional electrodes often suffer from:
- Rapid consumption
- Higher power consumption
- Frequent maintenance
- Reduced chlorine efficiency
DSA anodes solve these problems by providing:
- Low chlorine evolution overpotential
- Excellent chloride resistance
- Stable dimensions
- Long service life
This results in improved plant productivity and lower operating costs.
