Advantages of Using MMO Titanium Mesh Anode

In recent years, MMO titanium mesh anode has emerged as a leading solution in the electrochemical industry, particularly in applications such as wastewater treatment, electroplating, cathodic protection, and chlor-alkali production. Known for its exceptional conductivity, corrosion resistance, and long service life, the MMO (Mixed Metal Oxide) titanium mesh anode is transforming the way industries approach efficiency and sustainability.

What Is an MMO Titanium Mesh Anode?
An MMO titanium mesh anode is an advanced type of dimensionally stable anode (DSA) composed of a titanium substrate coated with a layer of mixed metal oxides such as ruthenium oxide (RuO₂), iridium oxide (IrO₂), or platinum group metals (PGMs). The mesh form increases the surface area, ensuring even current distribution and enhanced electrochemical performance.

Key Features of MMO Titanium Mesh Anode
High Electrical Conductivity

Outstanding Corrosion Resistance

Lightweight and Flexible Structure

Long Service Life in Harsh Environments

Environmentally Friendly and Recyclable

How Is MMO Titanium Mesh Anode Manufactured?
1. Titanium Mesh Selection
The process begins with selecting high-purity titanium mesh, typically Grade 1 or Grade 2, known for its formability and corrosion resistance.

2. Surface Pretreatment
To ensure proper adhesion of the MMO coating, the titanium mesh undergoes a multi-step pretreatment process, including:

Acid etching

Drying

3. MMO Coating Application
The mixed metal oxide solution is applied uniformly using techniques such as:

Brush coating

This is followed by thermal decomposition at elevated temperatures (400–600°C), forming a highly conductive and stable oxide layer.

4. Quality Control and Testing
Each MMO titanium mesh anode undergoes strict inspection for coating thickness, adhesion, and electrochemical activity to meet ISO and ASTM standards.
