MMO Coated Titanium Anodes
MMO coated titanium anode is one of the DSA anode, it is coated with mixed metal oxide coatings such as ruthenium iridium, iridium tantalum on the titanium substrate.
MMO coated titanium anodes were originally developed for chlorine production by seawater electrolysis and have been used in cathodic protection (CP) applications since the 1980s. MMO coated titanium anodes are used in a variety of environments, including seawater, brackish water, freshwater, carbon backfill and concrete, due to their significant advantages. Dinol can design and customize various sizes of the coated titanium anodes. We offer our customers MMO tube anodes and other titanium anodes, among others.

The auxiliary anode has gone through the development stages of iron and steel anode, graphite anode, high silicon cast iron anode and metal oxide coating anode. with the application of new materials and new technology, the auxiliary anode has improved obviously from current efficiency to service life.
Lead dioxide electrode has the characteristics of low resistivity, stable chemical properties, good corrosion resistance, good electrical conductivity, and can pass large currents, which substantially improves the bonding power of the plating.
Platinum is preferred for the outer surface of the anode because it is highly resistant to corrosion and ensures that current flows through most electrolyte media without causing it to form an insulating layer of its own.
