　　MMO anode use: the main body is coated with a mixed metal oxide IO2 / tantalum oxide Ta2O5 titanium anode, anode working life and rated current is determined by the anode body. MMO main anode must be titanium, shall not use copper core material. That is, the mixed metal oxide must be coated on the titanium substrate rather than on the surface of the copper core material.

　　The anode body is composed of a continuous titanium matrix. Titanium substrate coating is able to adapt to high thermal environment, crystal structure is stable, with catalytic and good conductivity of iridium / tantalum metal oxide mixture,

　　Specifications: Φ25 * 1000mm
