What is titanium anode?
Titanium anodes are electrochemical devices designed to replace traditional electrodes (such as graphite and lead-based electrodes). Unlike conventional electrodes, they effectively overcome the problems of high oxygen and chlorine evolution overpotentials and rapid corrosion and loss in electrochemical reactions. Their core advantages include a chlorine evolution overpotential ≤1.13V (vs SCE), a lifespan of 2-20 years, and energy consumption reduction of over 20%.
The titanium anode electrode consists of a high-purity titanium substrate and a noble metal electrocatalytic coating, which can resist corrosion from highly corrosive media (such as acid, alkali, and salt solutions), preventing rapid dissolution and failure of the electrode. It is equipped with highly conductive connection terminals, which facilitates efficient electrocatalytic reactions under various operating conditions (such as acidic/alkaline solutions and high current density environments).
Titanium anodes also have many other names, including Size Stable Anode (DSA), Size Stable Electrode (DSE), Coated Titanium Anode, Noble Metal Coated Titanium Anode (PTMA), Noble Metal Coated Anode (NMCA), Insoluble Titanium Anode, Oxide Coated Titanium Anode (OCTA), and Active Titanium Anode (ATA).

MMO Coated Titanium Anodes
Initially, customers need to choose between two core technology solutions for high-volume applications: ruthenium-coated titanium anodes and iridium-coated titanium anodes. Here are the key differences between the two:
Ruthenium Iridium Coated Titanium Anodes
Ruthenium oxide titanium anodes are specifically designed for chlorine precipitation reactions in salt solutions, exhibiting excellent performance in water treatment and swimming pool disinfection. This coating boasts exceptional stability and a service life of 2-20 years.
Applications include: electrolytic descaling of circulating water systems, on-site chlorine dioxide production, fruit and vegetable disinfection, electrolytic oxidation of water (EOW), chlor-alkali industries, and sodium hypochlorite generators.
Iridium Oxide Titanium Anode
Iridium oxide titanium anode is also called iridium tantalum titanium anode. It uses a high-temperature sintering process to coat a layer of iridium oxide on the titanium substrate. It focuses on oxygen evolution reaction in a strong acid/strong alkali environment. It has stronger corrosion resistance, low oxygen evolution potential, and will not produce any impurities during metal extraction.
Application areas: electroplating, wastewater treatment, electrochemical surface treatment of metal foils, electrolytic copper foil, aluminum foil, electrolytic production and recycling of non-ferrous metals, electrolytic copper recovery from etching solutions, organic electrosynthesis, electrodialysis, cathodic protection, PEM electrolytic cells and PCB electroplating.
Platinized & Specialized Electrodes
Our factory employs High-Temperature Electrolysis (HTE) or physical deposition techniques to manufacture high-precision platinum coated titanium mesh and platinised titanium anodes. Our electrodes exhibit exceptional electrical conductivity and chemical stability, making them the preferred anode material for the precision surface treatment industry.
Platinized Titanium Anodes
platinum coated titanium electrode are produced by sintering a thick platinum layer onto a titanium substrate. This results in a higher purity platinum layer than pure platinum, a uniform surface, excellent adhesion, and high ductility. In oxygen and chlorine evolution environments, it can uniformly conduct current, making it suitable for demanding applications such as high-precision electroplating and seawater cathodic protection. It supports long-term operation at high current densities and has a longer service life.
Applications: Chlorine electrolysis plants, breweries, paper mills, reagents, electroforming (microstructures, hollow jewelry, dental work), electroplating (circuit boards, chromium, copper, zinc, nickel, gold, silver, etc.), electrochemical synthesis (electrooxidation, detoxification), electronics and semiconductor industries, electrolytic deposition.
lead Dioxide Anode
We specialize in manufacturing long-life titanium-based lead dioxide (Ti/PbO2) anodes. These anodes employ an intermediate layer combined with an α-PbO₂ + β-PbO₂ active layer, ensuring excellent coating adhesion; compared to conventional lead anodes, they achieve a current efficiency of up to 95%.
Ti/PbO2 Lead Dioxide Titanium Anodes
Lead dioxide titanium anodes (PbO₂ electrodes) are specifically designed to meet the demands of highly corrosive environments and high oxygen evolution overpotential (OER) conditions. These anodes feature an optimized coating, offering sustainability, energy efficiency, reduced manual labor, and improved product purity. They also eliminate the need for cobalt sulfate in the electrolyte. Furthermore, unlike traditional lead anodes, they do not contaminate the cathode products.
Applications: Electrolytic refining, hydrometallurgy, metal refining, high-efficiency mining, electrolytic extraction, electrolytic production, wastewater treatment, perchlorate production.
Titanium Cathodes & Specialized Components
You can choose titanium cathodes and specialty electrode components from us, depending on the component type. We are one of the top manufacturers of titanium-based electrode components.
Titanium-clad Copper Rod
Titanium-clad copper is ideal for use as the conductive rod in high-current electrolytic cells. Its structure consists of an outer layer of titanium and an inner layer of copper, similar to a “titanium skin wrapped around a copper core,” combining the high conductivity of copper with the corrosion resistance of titanium. Furthermore, they can be customized to meet complex customer requirements.
Applications: Water electrolysis, chlor-alkali production, salt production, sodium hypochlorite generators, electroplating anodizing, hydrometallurgy (electrolysis of copper, zinc, and nickel), environmental electrochemistry (electrocatalysis, electro-Fenton oxidation, electro-oxidation), seawater desalination, marine engineering, shipbuilding, chemical industry, pickling.
Titanium Anode Basket
titanium baskets are manufactured using expanded metal mesh with a purity of up to 99.6% and an opening ratio of 60%-80%. They are lightweight, corrosion-free, and dimensionally precise. The products employ a precision TIG welding process, resulting in low voltage loss and high anode efficiency. Compared to ordinary titanium baskets, their structure is more robust, stronger, more durable, and will not deform during lifting operations.
Applications: Electroplating, electrolytic refining, circulating water treatment, metal recycling, anodizing, chemical processinga
Custom titanium electrode parts
Customized titanium electrode components have a wide range of applications. For example, in PCB manufacturing, they ensure uniform current distribution; in fine chemicals, they are used in electroplating or electrolysis production lines to adapt to complex operating conditions.
Industrial Application Solutions

Cathodic Protection Anodes (ICCP)
Cathodic Protection Anodes (ICCP) are suitable for highly corrosive environments such as seawater and soil. Mmo coated titanium anodes for cathodic protection feature a titanium-based coating with precious metals, and their strip/line structure facilitates even current distribution for cathode protection. They offer fast-response cathodic protection, are easy to maintain, and extend facility lifespan.
Applications: Oil and gas, marine engineering, municipal and infrastructure projects, energy and chemical facilities, high resistivity soils (desert/rocky areas), reinforced concrete structures (marine facilities/bridges), and corrosion protection for buried pipelines and storage tanks.
Water Treatment & Electrolyzer Anodes
Water treatment and electrolyzer anodes are typically the preferred choice for municipal water utilities and hydrogen electrolyzer industries, suitable for applications requiring efficient chlorine and oxygen evolution, low energy consumption, and zero pollution. Furthermore, they are also well-suited for cyclical applications involving frequent start-stop cycles and high current densities.
Applications: Ballast water treatment, industrial wastewater reuse, municipal reclaimed water treatment, and water disinfection.
Manufacturing Capabilities & Technical Specifications
Xubo Titanium Industry’s stringent control over anode quality stems from our meticulous management of the production process. We employ a precise coating process, applying 15 to 25 layers of coating before isothermal sintering at 500℃ to 600℃ to ensure that the precious metal oxides achieve nanoscale-level precise stoichiometry. This guarantees the uniformity of the coating and ensures that it remains intact and does not peel off even under extreme operating conditions.
Coating Selection & Performance Matrix
All four types of electrodes utilize a high-purity titanium substrate (Ti ≥ 99.6%, conforming to ASTM Class 1/2 standards). The specific performance characteristics of each electrode—especially under various electrolytic environments—depend on the nature of its noble metal coating: Ruthenium-iridium (Ru-Ir) coated titanium anodes are characterized by rapid and cost-effective sterilization; Iridium-tantalum (Ir-Ta) coated titanium anodes offer excellent resistance to strong acids; platinum-plated titanium anodes are specifically designed for noble metal plating applications; and lead dioxide (PbO2) anodes are the optimal choice for metal electrolysis. You can evaluate the following criteria based on your industry’s specific requirements to select the electrode best suited to your needs.
