Mmo Anode
Shaanxi CXMET Technology Co., Ltd. offers high-performance MMO (Mixed Metal Oxide) ribbon anodes, designed for cathodic protection systems in aggressive environments. These anodes are manufactured using ASTM B265 Grade 1/2 titanium substrates and coated with a highly conductive and corrosion-resistant IrO2/Ta2O5 mixed metal oxide layer. Known for their exceptional stability, low wear rates (1-6 mg/A.a), and long service life under high current density, our MMO ribbon anodes are ideal for applications like tank bottom protection.
Strong coating adhesion
Uniform coating thickness (>2μm)
Long lifespan even in chloride-rich conditions
Excellent electrical conductivity
Compatible with high current outputs
Simple installation and maintenance
Customizable according to service life and application environment
Uniform Current Distribution: Ensures even protection of the structure by minimizing potential gradients.
Chlorine/Oxygen Evolution: Depending on the environment, the anode enables Cl2 or O2 production to assist in surface reactions.
Stable Output Over Time: Maintains steady electrical output for long-term protection.
High Load Capacity: Supports large-scale infrastructure projects with high current demand.
MMO ribbon anodes from Shaanxi CXMET Technology Co., Ltd. offer several compelling advantages. The use of ASTM-certified titanium substrates ensures mechanical robustness and corrosion resistance.
Manufacturing Process & Production Flow Our MMO ribbon anodes are manufactured through a precise multi-stage process:
Titanium Substrate Preparation: ASTM B265 Grade I/II titanium sheets are slit into standard-width ribbons and cleaned to remove oxides.
Surface Treatment: A series of chemical etching and rinsing steps improve adhesion by increasing surface roughness.
Coating Application: IrO2 and Ta2O5 precursors are applied via brush or dip coating, layer by layer, ensuring uniformity.
Thermal Treatment: Coated ribbons are sintered in a controlled atmosphere furnace at elevated temperatures to form the stable MMO layer.
Repeat Coating Cycles: Multiple cycles ensure desired thickness and catalytic activity.
