MMO Ribbon Anode

Product Introduction

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.

Corrosion resistance

 

 

Titanium anodes resist corrosion in harsh environments, ensuring long service life and consistent electrochemical efficiency.

Simple installation and maintenance

 

Titanium anodes are easy to install and maintain, reducing downtime and simplifying system operation and servicing.

Long use time

 

 

Titanium anodes offer long service life, maintaining performance over time and reducing replacement frequency and maintenance costs.

Product Usage

MMO ribbon anodes must be used with backfill materials to optimize their performance. Direct burial without backfill can cause rapid corrosion and reduced lifespan. Proper backfill, such as gypsum and sodium sulfate, enhances current efficiency and uniform corrosion of the anode surface. Ribbon anodes are often paired with magnesium or zinc sacrificial anodes to reduce grounding resistance. When installed along pipelines, connection intervals should not exceed 305 meters to prevent resistance build-up over time.

Product Parameters

Product Functions

Cathodic Protection: Prevents corrosion of buried or submerged metallic structures by acting as the primary current-discharging anode.

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.

 

 

Product Advantages

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.

 

Welding with Conductive Strips: Conductive titanium strips are welded crosswise using high-precision spot welders.

 

Final Inspection: Coating thickness, adhesion, and conductivity are tested to ASTM and customer standards.

 

Packaging: Finished products are carefully packed for safe global shipping.

​​​​​​Product Applications

Tank Bottom Cathodic Protection

Underground Pipelines

Marine Structures (e.g., piers, jetties)

Bridges in Saltwater Zones

Water Treatment Facilities

Tunnels and Underground Structures

Offshore Wind Power Foundations

Desalination Plants

Anode products in seawater typically evolve chlorine (Cl2), while in soils and fresh or brackish waters, oxygen (O2), chlorine, or both may be released depending on the electrolyte composition.
