MMO Titanium Anode

The Expanded Metal Titanium Anode (MMO Anode) is a high-performance device designed for electrochemical applications requiring exceptional conductivity, chemical stability, and corrosion resistance. Manufactured by coating a high-purity titanium substrate—such as a solid plate or expanded mesh—with multiple layers of metal oxides including RuO₂, IrO₂, or PtO₂, these anodes efficiently conduct electricity while catalyzing targeted reactions such as the production of chlorine, oxygen, or other industrial products.

MMO Titanium Anodes are widely applied across industries including marine, oil and gas, water and wastewater treatment, power generation, chemical processing, and infrastructure protection. Their robust design ensures resistance to highly oxidative or acidic environments, making them ideal for cathodic protection, electroplating, electrolysis, and other electrochemical processes. Their long service life, combined with low maintenance requirements, offers a cost-effective solution for large-scale industrial operations.

Process Overview

The production of MMO Titanium Anodes follows a rigorous multi-step process to ensure durability, high conductivity, and long-term electrochemical performance. Each anode undergoes strict quality control at every stage:

1. Substrate Preparation: Titanium sheets or meshes are inspected for purity, surface smoothness, and structural integrity. Acid pickling and degreasing remove oxides and contaminants.
2. Surface Treatment: Sandblasting or chemical etching enhances surface roughness to improve oxide layer adhesion.
3. MMO Coating Application: Multiple layers of metal oxide precursors (Ru, Ir, and optional Pt) are applied via brushing or spraying to achieve uniform thickness.
4. Thermal Curing: Each coating layer is cured in high-temperature ovens to convert metal salts into conductive ceramic oxides.
5. Quality Testing: Adhesion, coating thickness, and electrochemical performance are verified through visual, mechanical, and non-destructive tests.
6. Optional Assembly: Pre-attached cables, centralizers, and other accessories are added based on customer requirements.
7. Packing & Shipping: Final anodes are wrapped in moisture-resistant materials and secured in reinforced crates for safe transport. Each unit is labeled with a unique serial number for traceability.

How to order mmo titanium anode?

Please Specify:

• Material: Titanium, Gr1, Gr2, etc.
• Type: Standard/Raised, Flattened
• Quantity: number of pieces – full size or cut pieces required
• Piece Size: width (SWD) x length (LWD)
• Shearing: bond or random. Please check the below photo for reference
• Finish: Pt coating, special, if any

Item No.: typically expanded metal is specified like the following examples:

1/8 #23 S 3′ SWD x 6′ LWD Titanium Gr 1

• – 1/8 inch= Short Way Of Diamond Dimension
• – #23 = Gauge (Usually not AWG, BWG, SWG, should be Washburn & Moen)
• – “S” = Standard (“F” would indicate flattened)
• – 3′ SWD x 6′ LWD = size of sheet width x length
• – Titanium Gr 1 = material
