Feinuotai's flagship coated anode -- ruthenium-based MMO coating on Grade 1 titanium substrate, manufactured in-house.
Ruthenium-based MMO (RuO₂ primary with modifier oxides) coated on Grade 1 titanium substrate by thermal decomposition. Best for chlorine evolution (lower overpotential than Ir-based). Primary applications: chloralkali brine electrolysis, desalination seawater chlorine production, water treatment disinfection, electroplating chlorine evolution anodes.
Supply Model: Grade 1 Titanium Substrate is the standard base material for all coated titanium anodes. Feinuotai manufactures Grade 1 titanium substrates in-house. Ru-based MMO and Ir-based MMO coatings are applied on Feinuotai's own in-house MMO coating line. Platinum, lead dioxide (PbO₂) and palladium coatings are supplied through Feinuotai's coating partners — not produced on-site.
Grade 1 CP titanium
RuO₂-based MMO thermal decomposition

Chlorine evolution — salt water, brine, seawater environments
Primary industrial application for Ru-based MMO anodes — chlorine generation in diaphragm, membrane and mercury cells.
Electrochlorination systems for marine growth prevention and water disinfection in desalination plants.
On-site chlorine generation for municipal and industrial water treatment facilities.
Grade 1 provides the best corrosion resistance in acidic/chloride environments + lowest residual stress for thin MMO adhesion. Grade 1 CP titanium is Feinuotai's standard substrate for all coated titanium anodes.
Ru for chlorine evolution (lower overpotential); Ir for oxygen evolution (higher overpotential). Specify your reaction type at inquiry.
Ru-based MMO applied on Feinuotai's own in-house MMO coating line — Grade 1 Ti substrate + in-house coating both Feinuotai scope.
Specify anode shape (sheet / mesh / plate / custom), dimensions, operating environment (brine / seawater / other), current density, and expected life. Coating composition and loading can be optimized for your specific cell design and process conditions.
