Description
MMO Titanium Anode Mesh is an advanced electrochemical material engineered for high-efficiency current distribution, extended service life, and superior corrosion resistance in industrial electrolytic systems. Manufactured by coating high-purity titanium mesh with a proprietary blend of mixed metal oxides (MMO) such as ruthenium, iridium, tantalum, and titanium oxides, this product delivers enhanced electrocatalytic performance and long-term chemical stability in harsh pH environments.
Unlike conventional anodes like graphite, lead alloy, or platinized electrodes, MMO titanium anode mesh offers 3–5 times longer operational lifespan with minimal maintenance and zero secondary pollution. Its open-grid expanded structure allows optimized fluid flow and gas release, ideal for high-throughput, continuous-flow systems.
💡 Common Applications Include:
-
⚡ Chlorine and sodium hypochlorite generation (Cl₂ / NaClO)
-
🌊 Electrochlorination in seawater treatment
-
🏭 Industrial wastewater oxidation
-
🛢️ Cathodic protection of pipelines and storage tanks
-
🔋 Electrolysis for hydrogen, oxygen, and alkali production
-
♻️ Metal ion recovery and selective electro-deposition
-
🧪 Electrochemical advanced oxidation processes (EAOPs)
MMO Titanium Anode Mesh is widely adopted in oil & gas, marine engineering, water treatment, mining, and energy industries as a high-efficiency, long-life titanium mesh anode solution.
⚙️ Material Composition & Coating Technology
The performance and durability of MMO coated titanium mesh depends on two critical components: the titanium substrate and the mixed metal oxide (MMO) catalytic layer. Each element is selected, processed, and applied to meet rigorous electrochemical demands in chloride-rich and acidic environments.
🧱 Titanium Substrate
| Parameter | Specification |
|---|---|
| Material Grade | Titanium Grade 1 or Grade 2 |
| Form | Expanded Mesh (Flattened / Raised) |
| Manufacturing Process | Cold rolling + acid pickling + mesh expanding |
| Mesh Size Options | 1×2 mm / 2×4 mm / 3×6 mm / custom |
| Thickness Range | 0.5 mm – 3.0 mm |
| Opening Ratio | 50% – 75% |
Grade 1 titanium offers excellent ductility and weldability, while Grade 2 provides enhanced mechanical strength with similar corrosion resistance. Mesh is expanded mechanically to form diamond-shaped openings, increasing electrode surface area and gas dispersion during electrochemical reactions.
🧪 MMO Coating Formulation
| Coating Component | Role in Electrochemical Process |
|---|---|
| RuO₂ (Ruthenium) | High chlorine evolution efficiency |
| IrO₂ (Iridium) | Enhances catalytic stability in acidic media |
| Ta₂O₅ (Tantalum) | Increases coating durability and adhesion |
| TiO₂ (Titanium) | Structural oxide, reduces internal stress |
The MMO layer is applied using a multi-step brushing and baking technique. This ensures uniform distribution, deep adhesion to the titanium surface, and long-term durability under fluctuating voltage or current cycles.
Coating thickness ranges from 5 to 12 μm, depending on the intended current density, pH level, and electrochemical load. Optional formulations focus on either chlorine evolution (Cl₂) or oxygen evolution (O₂) reactions, ensuring process-specific performance.
📐 Standard & Custom Specifications
MMO Titanium Anode Mesh is available in a wide range of standard configurations and fully customizable formats to meet the needs of specific electrolytic systems, tank geometries, and current densities.
