Premium Quality Titanium Cathodes from China - Reliable Suppliers & Factory for Titanium Clad Copper Hanger Bars and Plates
Product Features
Titanium exhibits outstanding corrosion resistance in oxidative media and chloride ion environments, and can withstand the long-term erosion of acidic electrolytes such as copper sulfate, nickel sulfate, and zinc chloride. A dense oxide film (TiO₂) forms easily on its surface, which is highly stable and has a long service life (typically over 5 to 10 years).
Titanium itself has a relatively high resistivity, but its conductivity can be significantly enhanced and the cell voltage reduced by applying special surface treatments, such as coating with noble metal oxide layers, thereby saving electrical energy. Common coating materials include ruthenium-iridium (Ru-Ir) and platinum (Pt), which possess both catalytic activity and stability.
Titanium has a density of only 57% that of steel, yet its strength is close to that of common steel. It is easy to install and transport, and can withstand mechanical stress during the electrolysis process. It has good rigidity and is not prone to deformation under long-term current, ensuring the stability of the plate spacing.
The surface can undergo treatments such as sandblasting and activation to enhance the adhesion of the coating, or be designed with specific patterns to facilitate gas release (such as hydrogen evolution during electrolysis). The coating can reduce the overpotential for metal deposition and increase current efficiency.
Long service life reduces replacement frequency and lowers maintenance costs. Titanium material is recyclable and requires less coating metal, meeting the requirements of green production.

Frequently Asked Questions
-
Q What makes titanium cathode plates superior to stainless steel cathodes in electrolytic processes? ▼Titanium cathode plates offer significantly better corrosion resistance than stainless steel, particularly in chloride-rich and acidic electrolyte environments such as copper sulfate and zinc chloride solutions. The naturally forming TiO₂ oxide layer provides long-term protection, whereas stainless steel can suffer from pitting and crevice corrosion. Additionally, titanium is 43% lighter than steel while maintaining comparable strength, making installation and handling easier. With a service life typically exceeding 5–10 years, titanium cathodes also reduce long-term maintenance and replacement costs.
-
Q What coating materials are commonly used on titanium cathode plates and why? ▼The most common coating materials applied to titanium cathode plates are ruthenium-iridium (Ru-Ir) oxide and platinum (Pt). These noble metal oxide coatings are chosen because they significantly enhance electrical conductivity, reduce cell voltage, and lower the overpotential for metal deposition. They also possess excellent catalytic activity and electrochemical stability, which increases current efficiency and extends the operational lifespan of the electrode. The choice of coating depends on the specific electrolytic application and the chemical environment involved.
-
Q How long is the typical service life of a titanium cathode plate? ▼Under normal operating conditions, titanium cathode plates typically have a service life of 5 to 10 years or more, depending on the electrolytic environment, current density, and maintenance practices. The dense and stable TiO₂ oxide film that naturally forms on the titanium surface is the primary factor contributing to this longevity. Regular inspection and proper surface maintenance can further extend the working life of the cathode plates, making them a cost-effective long-term investment for industrial electrolytic operations.
-
Q In which industries are titanium cathode plates most widely used? ▼Titanium cathode plates are most widely used in hydrometallurgy (including copper, zinc, nickel, cobalt, and manganese electrolytic refining and extraction), the electroplating industry, the chlor-alkali industry, electrochemical water treatment (such as electrocoagulation and electro-Fenton processes), and the preparation of new energy materials including electrolytic manganese dioxide and hydrogen production via water electrolysis. Their versatility across these demanding industries is a direct result of their exceptional corrosion resistance, mechanical strength, and adaptable surface coatings.
-
Q Are titanium cathode plates environmentally friendly and recyclable? ▼Yes, titanium cathode plates are considered environmentally friendly for several reasons. Titanium is a fully recyclable material, and its long service life significantly reduces the frequency of replacement, thereby minimizing industrial waste. The coatings used require only small quantities of precious metals, reducing resource consumption. Furthermore, their high current efficiency contributes to lower energy usage during electrolysis, aligning with the goals of green manufacturing and sustainable industrial production.
-
Q What surface treatments are applied to titanium cathode plates to improve performance? ▼Titanium cathode plates undergo several surface treatment processes to optimize their performance. Sandblasting is commonly used to roughen the surface, improving the mechanical adhesion of the applied coating. Chemical activation treatments prepare the surface for better bonding with noble metal oxide coatings. The surface may also be designed with specific textured patterns or microstructures to facilitate gas release during electrolysis, such as hydrogen evolution, which helps maintain stable current distribution and improves overall electrolytic efficiency.
