Long-Lasting MMO Coating – The High-Stability, Full-Scenario Core Coating for Titanium Anodes
Our MMO (Mixed Metal Oxide) coating boasts exceptional chemical stability and performs reliably in environments like soil, mud, freshwater, and seawater (even in low-pH acidic conditions). Sintered from a blend of precious metal oxides (e.g., iridium, tantalum, ruthenium), our MMO coating has been verified by independent laboratory accelerated life tests to outperform comparable products on the market.
We can produce anodes with different nobel metal oxide ratios and differing coating thickness as specific required.:
Ir-Ta Mixed Oxide Catalyst: Ideal for low-chloride/no-chloride environments (e.g., soil, freshwater), balancing stability and cost-effectiveness;
Ir-Ru Mixed Oxide Catalyst: Engineered for harsh conditions (e.g., seawater, highly acidic environments, chloride/oxygen-containing scenarios) with maximum corrosion resistance.
Note: We support customization of noble metal oxide ratios and coating thickness according to your specific requirements.Technical Specification Comparison Table
