Basic Product Knowledge
Titanium anodes are high-performance electrochemical electrodes composed of pure titanium substrate (Grade 1/Grade 2) and precious metal mixed metal oxide (MMO) catalytic coatings. Compared with traditional lead, graphite and magnesium anodes, they feature excellent corrosion resistance, low cell voltage, low power consumption, high current efficiency and long service life. They also produce no pollution during operation, ensure high purity of electrolytic products, and their titanium substrate can be reused after recoating, greatly reducing overall operating costs.
We offer a full range of titanium anode products, including plate type, mesh type, tube type, rod type and strip type titanium anodes. All specifications can be customized according to customer drawings and working conditions. Common coating types cover ruthenium-iridium, iridium-tantalum, platinum and other composite coatings to adapt to different electrolyte environments.
The service life depends on working current density, electrolyte composition, temperature and operating environment. Under standard industrial working conditions, conventional ruthenium-based coated anodes last 1–3years, and high-performance iridium-based coated anodes can serve 3–20 years, far longer than conventional sacrificial anodes. Stable operation and standardized maintenance can further extend their service life.
Selection & Application Guidance
The coating selection is based on your electrolyte environment:
1) Ruthenium-iridium coating: Ideal for chloride-containing environments (seawater desalination, brine electrolysis, wastewater dechlorination) with high catalytic activity and cost performance;
2) Iridium-tantalum coating: Suitable for strong acidic, high-temperature and high-corrosion environments (sulfuric acid electrolysis, industrial wastewater treatment) with ultra-strong corrosion resistance;
3) Platinum coating: Applied in high-precision electroplating and ultra-pure water preparation scenarios requiring stable performance.
Titanium anodes are widely applied in all electrochemical industries, including wastewater treatment (organic wastewater degradation, heavy metal removal), electroplating industry (copper, nickel, zinc electroplating), seawater desalination and anti-fouling, brine electrolysis, chemical electrolysis, cathodic protection of ships and pipelines, as well as swimming pool water disinfection and electrolytic sterilization.
Yes. Our high-quality MMO titanium anodes support stable operation within a temperature range of 10–60℃ and can adapt to high current density working conditions. Custom high-temperature resistant coatings are available for extreme high-temperature and high-load industrial scenarios to ensure continuous and efficient operation.
Customization & Technical Support
Absolutely. We provide one-stop customized services, including personalized customization of anode shape (plate, mesh, tube, special shape), size, substrate thickness, coating type and coating area. We can produce according to customers’ drawings, samples and actual working condition parameters to meet the needs of special industrial scenarios.
We can provide detailed technical data including anode size specifications, coating thickness, current density range, working voltage, service life parameters, electrochemical performance test reports, and corrosion resistance test data. We also provide professional parameter matching suggestions according to customers’ electrolytic tank size, electrolyte formula and production requirements.
