The titanium anode is the anode in the titanium-based metal oxide coating. According to the different catalytic coatings on the surface, it has the function of oxygen evolution and chlorine evolution. Generally, electrode materials should have good electrical conductivity, small change in pole pitch, strong corrosion resistance, good mechanical strength and processing performance, long life, low cost, and good electrocatalytic performance for electrode reactions. Titanium is the most suitable for the above comprehensive The required metal is generally industrial pure titanium Gr1 and Gr2.
