Ir oxideTitanium Tubular Anode
Ir oxide Titanium Tubular Anode Titanium tube is as the base material.Titanium mesh anode can be classified by coating,
Product Introduction
Titanium tubular anodes are dimensionally stable anodes (DSA) based on a titanium substrate coated with noble metal oxides. According to the surface catalytic coating, they can be classified into oxygen evolution anodes and chlorine evolution anodes.
In general, an ideal electrode material should offer:
Good electrical conductivity
Minimal change in electrode spacing
Strong corrosion resistance
High mechanical strength and good processability
Long service life
Low operating cost
Excellent electrocatalytic performance
Among available metals, industrial pure titanium (ASTM B265 Grade 1) best meets these comprehensive requirements and is therefore widely used as the base material.
Role of the Metal Oxide Coating
The noble metal oxide coating applied to the titanium substrate provides several critical advantages:
Low resistivity and high conductivity (compensating for titanium's relatively poor electrical conductivity)
Stable chemical composition and crystal structure
Dimensional stability of the electrode during operation
Excellent corrosion resistance
Long service life
Superior electrocatalytic activity, which reduces the overpotential for oxygen and chlorine evolution reactions and significantly lowers energy consumption
Base Material
Titanium tube is used as the base material, offering high strength, corrosion resistance, and uniform current distribution.
Classification by Coating
Titanium tubular (or mesh) anodes can be classified according to the coating material:
Platinum (Pt) coating
Ruthenium oxide (RuO₂) coating
Iridium oxide (IrO₂) coating
Applications
Titanium tubular anodes are widely used in various electrochemical and environmental applications, including:
Copper foil production
Electroplating processes
Chlor-alkali industry
Sodium hypochlorite generators
Water electrolysis systems
Functional water machines
Sewage and wastewater treatment
Swimming pool disinfection
Copper recovery from etching solutions
Organic electrosynthesis
