Baoji Yibaite New Materials specializes in premium MMO (Mixed Metal Oxide / precious metal oxide) coated titanium anodes, also known as DSA dimensionally stable anodes. Rooted in Baoji's titanium industry cluster, we adopt Grade1/Grade2 pure titanium substrates and advanced thermal decomposition coating technology to produce high-performance insoluble anodes that widely replace platinum-plated, lead and graphite electrodes for electroplating, electrolysis and water electrolysis hydrogen production.
Our MMO titanium anodes integrate ultra-low reaction overpotential, high current resistance, zero electrolyte contamination and long service life. Multiple coating systems are available to match acidic, alkaline and chloride-containing working environments, delivering obvious energy-saving and cost-cutting benefits for continuous mass production lines.
Main Coating Series (Customizable)
Iridium-Tantalum Coating (IrO₂-Ta₂O₅, Oxygen Evolution Type)
It is the company's main best-selling product, used for copper foil post-treatment, PCB acid copper plating and water electrolysis. Tolerating high current density up to 10,000 A/m², working stably in strong acid and alkaline baths, and bearing long service cycle for heavy-duty production.
Ruthenium-Titanium Coating (RuO₂-TiO₂, Chlorine Evolution Type)
Optimized for brine electrolysis, sodium hypochlorite generators and wastewater treatment. Low chlorine evolution potential, strong chloride corrosion resistance and competitive cost.
Platinum & Platinum-Iridium Composite Coating
Ultra-clean grade for semiconductor copper plating, precision gold/rhodium plating. No impurity dissolution, fully meets high-end electroplating purity standards.
Ir-Ru-Ta multi-component composite coating
For mixed electrolyte systems with both oxygen and chlorine evolution reactions.
Core Product Advantages
Remarkable Energy Saving & High Efficiency
Low oxygen/chlorine overpotential reduces cell voltage by 10–20% under identical current density. Mass production data from alkaline copper foil plating lines verifies stable power consumption reduction, bringing considerable electricity savings in long-term operation.
Long Service Life & Low Maintenance
Pure titanium base forms a passive anti-corrosion film; dense MMO coating thickness ranges 18–40 μm with strong adhesion, resisting peeling and corrosion. No frequent replacement required, cutting production downtime and maintenance expenses. Recoating service is supported after coating aging to reuse the titanium substrates.
Pollution-Free, Protect Electrolyte Purity
Iridium-based ceramic oxide active layer features extreme chemical stability, barely dissolving in acid or alkali. Hardly releases metal impurities into plating baths, effectively avoiding cross-contamination, ideal for impurity-sensitive high-precision electroplating processes. Classified as a clean anode equal to platinum electrodes.
Outstanding Cost Performance
Compared with platinum-plated electrodes, the initial procurement cost is much lower. Long service cycle minimizes replacement frequency, delivering better overall economic benefits over the full service life. High current density tolerance supports higher production output without expanding the equipment footprint.
