mmo coated titanium anodes

MMO coated titanium anodes provide advanced electrochemical solutions for modern industry

MMO (Mixed Metal Oxide) coated titanium anodes are essential components used in a variety of high-demand industries, including electrochemical processes, wastewater treatment, and seawater desalination. These anodes are made from titanium substrates coated with a combination of precious metals such as ruthenium and iridium, offering superior durability, corrosion resistance, and high efficiency in electrolysis processes. Known for their excellent performance in harsh environments, MMO coated titanium anodes are widely used in applications like electrowinning, electroplating, and chlorine generation.

At Baoji City ShenAo Metal Materials Co., Ltd., we manufacture premium products, designed to meet the rigorous demands of our customers across various industries. Our advanced production processes ensure each anode delivers exceptional longevity, reliable performance, and high efficiency.

MMO coated titanium anodes consist of two primary components:

Titanium Substrate – Titanium is chosen for its exceptional corrosion resistance and mechanical strength. It provides the structural foundation of the anode.

Mixed Metal Oxide Coating – A thin, precisely engineered layer of mixed metal oxides such as iridium oxide, ruthenium oxide, or tantalum oxide is applied to the titanium surface. This coating enhances the electrochemical activity and conductivity of the anode.

Manufacturing Process of MMO Coated Titanium Anodes

1. Titanium Preparation

High-purity titanium sheets, rods, or meshes are selected as the substrate. The titanium undergoes surface treatment such as sandblasting or acid etching to remove oxide layers and contaminants, ensuring proper adhesion of the coating.

2. Application of Mixed Metal Oxide Coating

The coating process is carried out using advanced techniques such as thermal decomposition, spray pyrolysis, or electrochemical deposition. The composition and thickness of the MMO coating are carefully controlled to match the intended application.

3. Heat Treatment

The coated titanium is heat-treated at high temperatures to stabilize the MMO layer, enhance adhesion, and optimize electrochemical properties.

4. Quality Control and Testing

Each anode undergoes rigorous quality checks, including adhesion tests, accelerated life testing, and electrochemical performance analysis, to ensure compliance with international standards.

Advantages of MMO Coated Titanium Anodes
1. High Durability

The combination of titanium and MMO ensures long-term stability even in harsh chemical environments.

2. Energy Efficiency

Due to their low overpotential, MMO coated titanium anodes reduce energy consumption in electrochemical processes.

3. Versatility

They can be manufactured in different shapes and sizes, making them suitable for diverse industrial needs.

4. Cost-Effectiveness

Although the initial investment may be higher than conventional anodes, the extended lifespan and reduced maintenance requirements significantly lower overall costs.

Industrial Applications of MMO Coated Titanium Anodes
1. Cathodic Protection

MMO coated titanium anodes are widely used in cathodic protection systems for offshore structures, pipelines, storage tanks, and marine vessels. Their ability to withstand seawater corrosion makes them indispensable in marine environments.

2. Electroplating

These anodes are used in decorative and functional electroplating industries for coating metals like gold, silver, nickel, and chromium. Their uniform current distribution ensures consistent plating quality.

3. Water and Wastewater Treatment

In electrochemical water treatment, MMO coated titanium anodes are employed for disinfection, advanced oxidation processes, and pollutant removal. They help achieve high efficiency without producing harmful by-products.

4. Chlor-Alkali Industry

MMO anodes are integral in chlorine generation, sodium hypochlorite production, and other chemical manufacturing processes due to their resistance to chlorine-induced corrosion.

5. Metal Recovery and Electrowinning

Used in hydrometallurgy, they enable efficient recovery of valuable metals such as copper, zinc, and manganese from ores and industrial waste.

6. Swimming Pool Chlorination

In residential and commercial swimming pools, MMO coated titanium anodes provide reliable chlorine generation for safe and cost-effective water disinfection.

MMO Coated Titanium Anodes Case Applications
1: Offshore Oil Platform

An offshore oil platform required long-term cathodic protection in highly saline conditions. MMO coated titanium tubular anodes were installed, achieving a service life of over 12 years without significant degradation.

2: Municipal Wastewater Treatment Plant

A large wastewater treatment facility adopted MMO coated titanium anodes for electrochemical oxidation. The anodes efficiently degraded organic pollutants and improved water quality while reducing operational costs.

3: Mining Industry

In a copper electrowinning plant, MMO mesh anodes enhanced current efficiency and reduced energy consumption, leading to higher recovery rates and increased profitability.
