Metal oxide-coated titanium electrodes are distinguished according to the gas precipitated by the anode in the electrochemical reaction. The chlorine gas precipitated on the anode is called the chlorine evolution anode, such as the ruthenium-coated titanium electrode, which is used for the oxygen evolution on the anode. For oxygen evolution anode, such as iridium-coated titanium electrode.

After years of factory production and research, it is found that compared with traditional graphite electrodes and lead-based alloy electrodes, titanium electrodes have the following advantages.

1.Titanium anode has stable dimension.The distance between electrodes donot change during electrolysis.This can ensure a a stable cell voltage.

2.Titanium anode has low voltage,so the power consumption can be reduced by 10%-20%.

3.Long working life.In the production of chlorine by diaphragm method,metal anodes resistant to chlorine anode alkali corrosion,and the anode life can reach more than 6 years,while graphite anodes are only 8 months.

4.Titanium anode can overcome the dissolution problem of graphite anode and lead electrode.This can avoid dissolution of electrolyte and cathode products.therefore,the purity of metal products can be improved.

5.Titanium anode can withstand high current dendity.

6.In chlor-alkali production,it can get higher quality production.The purity of chlorine is higher,with no carbon dioxide,with higher alkali concentration,saving energy consumption.

7.Titanium anode can work in many corrosive and special electrolytes.

8.Titanium anode can avoid short circuit problem after the lead electrode is deformed,thus improving the current efficiency.

9.Titanium anode is light in weight,which can reduce labor intensity.

10.Titanium anode can work in the high temperature and high current density of chlorate electrolyzer.

11.Low overpotential characteristics.The bubbles between the electrodes and the surface are easy toremove.SO the cell voltage is reduced.
