The key role of metal oxide coating on titanium anode is analyzed

Titanium anodes, also known as DSA anodes because of their lightweight and flexible manufacturing process, have significant advantages over other similar anodes.

First, the dimensional stability of the titanium anode is high, and the electrode spacing is constant during the electrolysis process, thus ensuring smooth electrolytic operation at a stable battery voltage. Secondly, its low operating voltage, small power consumption, DC power consumption can be reduced by 10-20%, effectively saving energy. Moreover, the titanium anode has a long service life and strong corrosion resistance, ensuring long-term stable operation.

In addition, the titanium anode overcomes the dissolution problem of the graphite anode and the lead anode, avoiding the pollution of the electrolyte and cathode products, thus improving the purity of the metal products. Its high current density, low overpotential and high electrode catalytic activity make the production efficiency significantly improved. At the same time, the titanium anode can also avoid the short-circuit problem that may be caused by the deformation of the lead anode, and improve the current efficiency.

The shape of the titanium anode is easy to make, the precision is high, and the titanium substrate can be reused, which reduces the production cost. More importantly, the titanium anode has a low overpotential characteristic, and the bubbles on the electrode surface are easy to eliminate, effectively reducing the voltage of the electrolytic cell. So what exactly does the metal oxide coating on the titanium anode do? It mainly enhances the electrical conductivity and electrocatalytic activity by covering different coatings, thereby promoting the electrolytic reaction process to ensure that the anode has a longer service life in different use environments and achieve the desired use effect.

As for the coating thickness, although the precious metal content is the key to ensure the normal operation of the anode product, the thickness is not a direct determining factor. The thickness of the coating mainly depends on the number of brushes and solvent concentration, and is not directly related to the precious metal content. Thicker coatings are more likely to fall off at the point of contact, so careful control is required during coating preparation to achieve the best results.
