One Stop MMO Disc Anode Factory - Wstitanium
In today’s industrial field, corrosion protection and electrochemical applications are crucial. As a high-performance product, MMO disc anode is playing an increasingly important role. With its deep technical accumulation and innovative spirit in the fields of materials science and electrochemistry, Wstitanium is committed to providing high-quality, customized one-stop MMO disc anode products and solutions to global customers.

Ruthenium-iridium MMO Disc Anode
With ruthenium and iridium oxides as coating, it has good chlorine evolution catalytic activity and stability, and performs well in chlorine-containing media, such as electrolysis of brine to produce chlorine, effectively reducing the chlorine evolution overpotential and improving current efficiency.

Iridium-Tantalum MMO Disc Anode
The oxide coating of iridium and tantalum makes it highly corrosion-resistant, especially in acidic environments. It is suitable for electroplating and other fields, and can work stably for a long time in strong acidic plating solutions to ensure the quality and uniformity of the coating.

Platinum MMO Disc Anode
It has extremely high catalytic performance and can adapt to a variety of complex electrochemical systems, but the cost is relatively high. It is often used in electrochemical analysis and electroplating processes that require high-precision electrochemical performance of the anode.
Advantages of MMO Disc Anode
MMO disc anode mainly consists of two parts: titanium substrate and MMO active coating. MMO active coating includes ruthenium (Ru), iridium (Ir), platinum (Pt), etc. These metal oxides each play a unique role. For example, ruthenium oxide has high catalytic activity for chlorine evolution reaction, and iridium oxide performs well in oxygen evolution reaction. By precisely controlling the proportion of each metal oxide and the coating structure, Wstitanium can optimize the electrocatalytic performance of the anode to meet the needs of different application scenarios.
- Larger effective reaction area
The disc-shaped structure has a larger surface area to volume ratio. Both its side and upper and lower surfaces can participate in the electrochemical reaction.
- Optimized current distribution
The disc-shaped geometry allows the current to flow out from all parts more evenly, avoiding the problem of local current concentration.
- Easy installation
In large electrolytic cells, multiple disc-shaped anodes can be arranged in an array to fully utilize the space while ensuring the overall electrochemical performance.
- Enhanced fluid dynamics
When the electrolyte flows in the electrolytic cell, the disc-shaped anode can promote the turbulence of the electrolyte and enhance the material transfer effect.
Custom Manufacturing MMO Disc Anode Specifications
Wstitanium offers a variety of standard specifications of MMO disc anodes to meet common application scenarios. The diameter of standard products usually ranges from 50 to 500 mm, and the thickness is between 5 and 20 mm. Different coating thicknesses and formulations can be selected according to different current density requirements. For example, for general ship cathodic protection applications, a standard disc anode with a diameter of 200 mm and a thickness of 10 mm can be selected. Its coating is optimized to stably provide the required protection current in seawater. In addition, Wstitanium also provides you with customized MMO disc anode solutions.

MMO Disc Anode Application
As a high-performance electrode material, MMO (Mixed Metal Oxide) disc anode has shown its indispensable value in many fields such as marine engineering, cathodic protection, shipbuilding, electroplating, sewage treatment, etc. Its unique chemical composition and physical structure give it excellent electrochemical performance, which has greatly promoted the technological progress and development of related industries.
Offshore
Offshore platforms are in the marine environment for a long time and are threatened by strong corrosion from seawater. MMO disc anodes are widely used in cathodic protection systems of offshore platforms. By connecting with the metal structure of the platform to form an electrochemical circuit, the anode continuously releases electrons to keep the metal surface of the platform in a cathodic state, thereby inhibiting metal corrosion.
Due to the strong seawater corrosion resistance of MMO disc anodes, they can work stably for a long time in harsh seabed environments, adapt to complex seabed terrain and water flow conditions, and ensure the long-term safe operation of submarine pipelines.

Ships
Installing MMO disc anodes on the bottom and sides of ships, which are prone to corrosion, can effectively inhibit the electrochemical corrosion of the hull metal and extend the service life of the hull. Compared with traditional sacrificial anode materials (such as zinc alloys), MMO disc anodes have higher current efficiency and longer service life, reducing the number of anode replacements, reducing the maintenance cost and downtime of ships. At the same time, the lightweight design of MMO disc anodes also helps to reduce the overall weight of the ship and improve the navigation performance and fuel economy of the ship.

Electroplating
As an insoluble anode, the MMO disc anode provides a stable current and uniform electric field distribution for electroplating. Taking the nickel plating process as an example, the oxidation reaction on the anode surface causes the nickel ions in the solution to be continuously added to the cathode (the workpiece to be plated) surface, thus achieving nickel electrodeposition. Compared with traditional soluble anodes (such as nickel plates), the MMO disc anode has a higher current efficiency and can deposit more metal ions on the workpiece surface in the same time, thus improving the electroplating efficiency.

Sewage treatment
MMO disc anode is mainly used in electrochemical oxidation technology in sewage treatment. By inserting MMO disc anode and cathode into sewage and applying a certain voltage, an oxidation reaction occurs on the anode surface to produce active substances with strong oxidizing properties (such as hydroxyl radicals, chlorine, etc.). These active substances can quickly decompose organic pollutants and harmful substances such as ammonia nitrogen in sewage, converting them into harmless substances such as carbon dioxide, water and nitrogen, thereby achieving the purpose of purifying sewage.

Whether it is the cathodic protection of offshore platforms and submarine pipelines in marine engineering to resist the ruthless corrosion of seawater, or the protection of hulls and seawater cooling systems in the shipbuilding industry to improve the safety and reliability of ship operations, or the realization of high-quality and efficient electroplating operations in the electroplating field to meet the stringent requirements of high-end manufacturing for plating, and the efficient purification of various types of sewage in the sewage treatment industry to help the development of environmental protection, the MMO disc anodes customized by Wstitanium have shown irreplaceable importance. Through customized services, we can accurately adjust the various parameters and performance indicators of the anode according to the unique needs of different industries and different application scenarios to achieve the best adaptation effect.
