The applications of Titanium in MMO Anodes
As anode substrates: Titanium have the advantages of low density, high strength, and strong corrosion resistance, which can provide a stable supporting structure for MMO anodes. This ensures that the anodes will not be damaged by factors such as corrosion and mechanical stress during use, thus prolonging the service life of the anodes.
- Improving electrical conductivity: Although titanium itself has moderate electrical conductivity, when used as the substrate of MMO anodes, the metal oxide coating on the surface has low resistivity and good electrical conductivity. This can effectively improve the electrical conductivity of the anodes, enabling the current to be evenly distributed on the anode surface and enhancing the electro – catalytic efficiency of the anodes.
- Achieving dimensional stability: The Titanium substrates are tightly bonded to the metal oxide coatings. They can maintain dimensional stability during the electrolysis process, avoiding changes in the electrode spacing in the electrolytic cell due to changes in the electrode size. This ensures that the electrolysis operation is carried out under a stable cell voltage, which is beneficial for improving the electrolysis efficiency and product quality.
- Adapting to different environments: The excellent corrosion resistance of Titanium enables them to adapt to various harsh electrolysis environments. For example, in electrolytes containing high – concentration chloride ions, MMO anodes made of Titanium can resist the erosion of chloride ions and work stably, ensuring the normal operation of the cathodic protection system.
Different titanium have different applications in MMO anodes due to their differences in composition and properties. For example, Titanium Alloy such as Grade 5, Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si and Ti-6.5A1-3.5Mo-1.5Zr-0.3Si, which have the characteristics of high specific strength, high – temperature resistance, and oxidation resistance, are suitable for some occasions with high requirements for anode performance, such as high – temperature electrolysis and electrolysis in strongly corrosive media.
