Ruthenium oxide coated titanium anode                is also called chlorine evolving titanium electrode. The most representative one is the ruthenium-iridium titanium anode. It is made by applying ruthenium and iridium containing salts on the surface of titanium metal, and after multiple coatings and high-temperature oxidation. The mixed metal oxide coating of ruthenium oxide and iridium oxide is obtained. The ruthenium oxide in the coating can effectively reduce the chlorine evolution potential during the electrolysis of chlorine, thereby increasing the potential difference between chlorine evolution and oxygen evolution, and acting as an electrocatalyst. The addition of iridium oxide effectively increases the service life of the titanium anode. At the same time, due to the excellent conductivity of the precious metal coating, the titanium electrode can carry larger currents, significantly improving electrolysis efficiency, thereby improving industrial productivity. At present, in addition to the most typical ruthenium-iridium coated titanium anodes, our company can also provide mixed oxide-coated titanium anodes of various elements.

Features and applications
 
Ruthenium-iridium titanium anodes are widely used in the chlor-alkali industry for their excellent electrocatalytic effect in chlorine evolution reactions. The active-coated titanium anodes have relatively low overpotentials for both chlorine and oxygen. When salt water is electrolyzed to generate chlor-alkali, the titanium anode is The overpotential of chlorine is low, 140mV lower than the graphite anode at 1A/㎡; the titanium anode can reduce the "bubble shielding effect" during use. The bubbles generated on the surface of the titanium anode are relatively small, which reduces the aeration between the titanium anode and the two poles. The resistance is significantly reduced and the electrolysis efficiency is improved.     
 
 
 
Ruthenium-iridium and titanium anodes are used in skid-mounted sodium hypochlorite generators and chlorine dioxide generators, making it possible to produce miniaturized electrolytic chlorine, avoiding the safety risks of long-term storage of sodium hypochlorite in enterprises, and are widely used in water plant disinfection and sewage treatment. Electrolysis treatment, reducing COD, BOD, etc.     
 
 
 
Ruthenium iridium-titanium anodes are used in electrolytic metallurgy in chloride solution systems. The anode precipitates chlorine gas and the cathode deposits high-purity metal. The titanium electrode consumes little energy, has high electrolysis efficiency and high single-cell productivity.     
 
 
 
Ruthenium-iridium titanium anodes are used in the field of impressed current cathodic protection. They are mostly used for the anti-corrosion of marine engineering facilities, anti-corrosion of underground pipelines, cathodic protection and anti-corrosion of reinforced concrete buildings, cathodic protection and anti-corrosion of ships, etc.     
 
 
 
Ruthenium-iridium titanium anodes are widely used in circulating cooling water. They can effectively remove calcium and magnesium ions in cooling, effectively improve the scaling situation in equipment, and at the same time produce a small amount of hypochlorite to disinfect and sterilize, effectively protecting equipment. running well.     
 
Titanium electrodes are used in EDI electrodialysis to produce fresh water.
