To achieve optimal results with titanium electrodes, it is necessary to have a thorough understanding of the available types. There are five main categories of titanium anodes, each with a unique surface catalytic coating. Let’s explore these varieties to unlock their full potential.
Ruthenium-iridium-coated titanium electrodes are widely used in various industries due to their excellent catalytic activity and high antioxidant capacity. These electrodes are commonly used in chlorine evolution occasions such as the Chlor-alkali industry, sewage treatment, sodium hypochlorite production, and cathodic protection.
There are different types of ruthenium coatings available for titanium electrodes, including Ru-Ti, Ru-Ir-Ti, Ru-Co-Ti, Ru-Sn-Ti, Ru-Si-Ti, Ru-Ti-Zr, Ru-Ti-La, and Ru-Ti-Ce. The selection of the appropriate ruthenium coating depends on the specific requirements of the application.
The standard formulation for ruthenium-iridium coated titanium electrodes is 8g of ruthenium and 2g of iridium per square meter, with an 8-micron coating thickness. This ensures a high-quality coating that provides excellent performance and durability in various environments. At Hele Titanium, we offer various customized solutions to meet our customers’ specific needs, ensuring high-quality and long-lasting electrodes.
Iridium tantalum electrodes are a type of titanium anode that is designed for use in electrolytic processes such as the extraction of non-ferrous metals, electroplating, and electrochemical reduction. These processes typically use electrolytes that contain highly oxidizing elements, such as sulfuric acid, nitric acid, and hydrogen peroxide, which require an anodic material with high corrosion resistance and low oxygen evolution overpotential.
Iridium-tantalum-coated titanium electrodes are the ideal solution for this requirement, offering excellent resistance to corrosion and high stability in harsh environments. There are different types of coatings available for these electrodes, including Ir-Ta, Ir-Ta-Co, and Ir-Ta-Sn. However, the most commonly used oxygen evolution electrode is the Ir-Ta-coated titanium electrode, which provides superior performance and durability.
At Hele Titanium, we specialize in manufacturing high-quality iridium-tantalum electrodes, for a wide range of industrial applications. Contact us today to learn more about our products and services.
Platinized titanium anodes are widely used in various industries due to their good electrocatalytic activity and corrosion resistance. The manufacturing process of platinum-plated titanium electrodes begins with selecting high-quality titanium mesh as the base material. The titanium mesh undergoes a series of surface treatments like sandblasting, degreasing, and pickling to prepare the surface for plating.
Next, a layer of platinum is electroplated onto the surface of the titanium mesh. The thickness of the platinum layer is generally 2-5μm, which ensures good electrochemical performance and a long service life for the electrode.
Platinum-plated titanium electrodes have a wide range of applications. In the electrolytic water field, they are used in the production of high-purity water and the electrolysis of seawater. In the organic synthesis field, they are used in electrochemical synthesis reactions. In the cathodic protection field, they are used to prevent corrosion of metal structures. In the electrolytic water hydrogen production field, they are used in the production of hydrogen from water.
Mixed Metal Oxide (MMO) Titanium Anodes are an extremely versatile solution, capable of providing effective support for cathodic protection, electroplating, electrolysis, water treatment, and electrodialysis. By applying a thin layer of mixed metal oxides, such as RuO2, IrO2, PbO2, and Ta2O5, onto a titanium substrate, these anodes become highly efficient in terms of electrocatalytic activity, electrical conductivity, and oxidation resistance. This makes MMO Titanium Anodes essential for various industrial applications as follows:
Lead Dioxide Titanium Anodes provide efficient oxidation and excellent corrosion resistance. With a lead dioxide coating on a titanium substrate, they excel in electroplating, electrowinning, and wastewater treatment. Their durability in harsh conditions makes them ideal for chlorine salt electrolysis and water treatment. This makes them a reliable option for a variety of electrochemical processes.
Used in electroplating, electrowinning, and wastewater treatment, they ensure precise metal deposition, sustainable resource extraction, and advanced water purification.
In chlorine salt electrolysis, they endure harsh conditions, producing chemicals and disinfecting water reliably.
