Description
Ru-Ir MMO Titanium Electrode for Efficient Industrial Brine Electrolysis Systems
Titanium Electrode for Brine Electrolysis Cell is a high-performance mixed metal oxide (MMO) coated titanium electrode specially designed for industrial brine electrolysis applications. The electrode uses high-purity titanium substrate coated with ruthenium-iridium precious metal oxides, providing excellent chlorine evolution efficiency, low operating voltage, outstanding corrosion resistance, and long service life in chloride-containing electrolyte environments.
This titanium electrode is widely used in brine electrolysis cells, sodium hypochlorite generators, seawater electrolysis systems, electrochlorination equipment, ballast water treatment systems, cooling water disinfection systems, and various industrial chlorine generation applications.
Compared with conventional graphite electrodes and lead-based electrodes, the Titanium Electrode for Brine Electrolysis Cell offers higher current efficiency, lower energy consumption, dimensional stability, and significantly longer operational life.
What Is a Brine Electrolysis Cell?
A brine electrolysis cell is an electrochemical system that converts sodium chloride solution into chlorine, sodium hypochlorite, hydrogen, and other oxidizing substances through electrolysis.
During operation:
- chloride ions are oxidized at the titanium anode,
- chlorine gas is generated,
- hydrogen is produced at the cathode,
- sodium hypochlorite can form in solution.
The electrode is one of the most critical components in the electrolysis cell because it directly influences:
- chlorine generation efficiency,
- cell voltage,
- power consumption,
- electrolysis stability,
- equipment lifespan.
Ru-Ir coated titanium electrodes are considered one of the most reliable and efficient solutions for industrial brine electrolysis cells.
