Why Titanium Be An Anode？

Titanium anode, also known as titanium metal oxide coated anode, is an anode that is coated on the surface of titanium substrate (e.g. titanium plate, titanium mesh, titanium rod, titanium tube, titanium wire, titanium disc, titanium strip, etc.) by using different precious metal ratios and coating thicknesses according to the customer’s application requirements and design life. They can carry out electrocatalytic reactions under specific environments and exhibit electrochemical functions such as oxygen and hydrogen precipitation.

Why Comes Out Titanium Anode?

Prior to the 1960s, anode materials consisted primarily of graphite anodes, lead dioxide electrodes, platinum electrodes and magnetic iron oxide electrodes. These traditional anode materials were widely used in electrolysis and electroplating. However, due to their high cost, high energy consumption, short service life, and performance limitations in highly corrosive environments, the application of these materials has gradually revealed many problems. These problems have led to the development of new anode materials such as anodes using titanium as a substrate as an alternative material. Titanium anodes not only effectively solve the problems of traditional materials, but also show significant advantages in terms of corrosion resistance, current density tolerance, service life, etc., which promotes the wide application of titanium anodes in many industrial fields.

What Is Titanium Anode Advantage?

1. First of all, titanium anode has good electrocatalytic activity and conductivity. Precious metals such as RuO₂, IrO₂, TaO₂, etc. coated on the titanium substrate are able to show excellent catalytic performance in the electrolysis process. When the current passes through the electrolyte, the noble metal catalyst on the anode can promote the oxidation reaction of electrons and greatly improve the reaction efficiency.

2. Through this electrocatalytic effect, titanium anode not only improves the overall performance of the electrolysis process, but also saves power consumption, and DC power consumption can be reduced by 10-20%.

3. Titanium anode has good dimensional stability during the working process of electrolyte. During the electrolysis process, the shape and size of titanium anode are almost unaffected and can maintain long-term stable performance. In addition, the spacing of the anodes is fixed by bolting, which ensures that there will be no change in the process of use.

4. Conventional graphite anodes tend to dissolve and release impurities during use, thereby contaminating the electrolyte. Titanium as an anode material has excellent corrosion resistance and is not easy to dissolve, which can effectively avoid contamination of the electrolyte. This characteristic helps to maintain the purity of the electrolyte, thus improving the purity of the metal product and ensuring high quality output in the production process.

5. Compared with other traditional metals, titanium substrate has a smaller density and lighter weight, as well as excellent corrosion resistance, able to work stably in the strong corrosive and special requirements of the electrolytic medium. In addition, titanium has excellent machinability, high mechanical strength, and is easily processed by laser cutting, wire cutting, turning and machining. Therefore, titanium can be easily processed into anodes of various shapes and designs to meet different application requirements.

6. The use of titanium as an anode can significantly extend its working life. In the diaphragm production industry, titanium anodes have a service life of more than 6 years, compared to 8 months for conventional graphite anodes. In addition, titanium anodes can have a service life of up to 50 years in cathodic protection applications, significantly reducing replacement and maintenance costs.

7. Titanium anodes are able to increase current density and maintain excellent performance and stability when electrolyzed at high working current densities and high temperatures. Its excellent corrosion resistance and thermal stability enable it to operate efficiently for long periods of time in harsh electrolysis environments, further enhancing electrolysis efficiency and the overall economics of industrial production.

What is Titanium Anode Application?

1. Chlor-alkali industry: As one of the largest industries in industrial electrolysis, titanium anode optimizes the production process of chlor-alkali, especially in the application of ionic membrane process, which greatly improves its industrialization level. The use of titanium anode not only improves the electrolysis efficiency, but also reduces energy consumption and maintenance costs, promoting the sustainable development of chlor-alkali production.

2. Cathodic protection: Titanium anode is an important applied current cathodic protection anode, which is widely used in soil, freshwater pipelines, concrete, storage tanks and other environments. Common forms of titanium anodes include titanium anode tubes, titanium anode wires, titanium anode strips, flexible titanium anodes, and titanium anode rods. These anodes can ensure uniform current distribution and adjustable output in application, and produce very little stray current, which will not cause corrosive interference to the surrounding structures, ensuring the stability and long-term reliability of the system.

3. The application of titanium anodes in the production of sodium hypochlorite is mainly through the generation of sodium hypochlorite in a salt-added or brine environment, thus realizing efficient sterilization and disinfection functions. The role of titanium anode in this process is crucial, and it is widely used in swimming pool water treatment, seawater aquaculture, sewage treatment and other fields.
4. Titanium anode is an indispensable key component in the production of metal foil, especially in the process of making copper foil by electrolysis. By providing stable current and excellent corrosion resistance, titanium anode ensures efficient electrolysis process and significantly improves the quality and production efficiency of copper foil.

5. Electroplating industry: In the electroplating industry, platinized titanium anodes are widely used in a variety of electroplating processes, especially in the fields of zinc plating, precious metal plating (e.g. gold plating, silver plating, palladium plating, etc.), hard chrome plating, nickel plating and tin plating.

In summary

In addition to the applications mentioned above, there are many other important applications for titanium anodes in the field of electrochemistry and electrometallurgy, which make full use of the excellent properties of the titanium substrate itself in conjunction with the coating of the precious metal.
