mmo coated titanium electrode

What Is an MMO Coated Titanium Electrode?

The MMO coated titanium electrode (Mixed Metal Oxide coated titanium electrode) is a highly advanced electrochemical material widely applied in industrial processes. Designed for durability, efficiency, and corrosion resistance, it combines a titanium substrate with a specialized mixed metal oxide coating. This innovative design ensures excellent conductivity, long service life, and stable electrochemical performance in harsh environments.

An MMO coated titanium electrode is composed of two critical layers:

Titanium substrate – Provides excellent mechanical strength, corrosion resistance, and a lightweight structure.

Mixed metal oxide (MMO) coating – Typically consists of ruthenium oxide (RuO₂), iridium oxide (IrO₂), or a combination of noble metal oxides. This coating significantly improves the electrode’s electro-catalytic activity and conductivity.

Manufacturing Process of MMO Coated Titanium Electrode

1: Titanium Substrate Preparation

High-purity titanium plates, tubes, or meshes are selected as the base material. The surface undergoes mechanical polishing, sandblasting, and chemical cleaning to remove oxides and impurities. This preparation guarantees strong adhesion between the titanium and the MMO coating.

2: MMO Coating Application

Using techniques such as thermal decomposition or brush-coating, a solution containing metal salts of ruthenium, iridium, and other oxides is applied. The electrode is repeatedly coated and baked at high temperatures to achieve uniform thickness and strong bonding.

3: Quality Testing

Electrodes are tested for adhesion strength, coating uniformity, and electrochemical performance. Laboratory tests such as accelerated life testing and current density analysis ensure the MMO coated titanium electrode meets international standards.

4: Customization

Depending on customer requirements, the coating composition, thickness, and electrode shape can be customized for specific applications, such as anode or cathode use in different electrochemical systems.

Advantages of MMO Coated Titanium Electrode

High electrical conductivity

Superior corrosion resistance

Excellent electro-catalytic activity

Long service life (up to 20 years depending on operating conditions)

Customizable coating compositions to match industrial needs
