1
Excellent Corrosion Resistance
Titanium exhibits outstanding corrosion resistance in oxidative media and chloride ion environments, withstanding 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 with a long service life (typically over 5 to 10 years).

Good Electrical Conductivity & Low Resistance
Titanium's conductivity can be significantly enhanced and cell voltage reduced by applying special surface treatments, such as coating with noble metal oxide layers, saving electrical energy. Common coating materials include ruthenium-iridium (Ru-Ir) and platinum (Pt), which possess both catalytic activity and stability.

QWhat is a titanium cathode plate and how does it work in electrolysis?+A titanium cathode plate is an electrode made from titanium substrate, often coated with noble metal oxides such as ruthenium-iridium (Ru-Ir) or platinum (Pt). In electrolysis, it serves as the cathode where metal ions in the electrolyte solution are reduced and deposited onto its surface. The titanium base provides structural strength and corrosion resistance, while the coating enhances electrical conductivity and catalytic performance.
-
QHow long is the 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. The dense TiO₂ oxide film that naturally forms on the titanium surface provides excellent corrosion protection, significantly extending the plate's lifespan compared to conventional cathode materials.
-
QWhat industries are titanium cathode plates most commonly used in?+Titanium cathode plates are widely used across multiple industries, including hydrometallurgy (copper, zinc, nickel, cobalt, and manganese electrolysis), the electroplating industry, the chlor-alkali industry, electrochemical water treatment for environmental protection, and the preparation of new energy materials such as electrolytic manganese dioxide and hydrogen production via water electrolysis.
-
QWhat coatings are applied to titanium cathode plates and what are their benefits?+The most common coatings applied to titanium cathode plates are ruthenium-iridium (Ru-Ir) oxide and platinum (Pt). These coatings offer dual advantages: catalytic activity that lowers the overpotential for metal deposition and increases current efficiency, and chemical stability that ensures long-term performance in harsh acidic or alkaline electrolyte environments.
-
QWhy is titanium preferred over other metals for cathode plates?+Titanium offers a unique combination of properties that make it ideal for cathode plates: it is lightweight (density only 57% of steel) yet high in strength, highly resistant to corrosion in both acidic and chloride environments, and its surface can be easily modified with functional coatings. Additionally, titanium is recyclable and environmentally friendly, making it a cost-effective and sustainable choice for long-term industrial use.
