Mixed Metal Oxide (MMO) Anode


    Mixed Metal Oxide Anodes (MMO Anodes) are anodes made by titanium coated with mixed

 metal oxide. It is a crystalline electrically-conductive coating that activates the titanium and

 enables it to function as an anode. MMO Anodes have an extremely low consumption rate.

 They are widely used in soil, sea, mud, sewage and fresh water environments, etc.


Advantages of Mixed Metal Oxide (MMO) Anodes: 

   -MMO coatings have high chemical stability even in environments with very low PH values;
   -The coating of mixed metal oxide anodes is not affected by chlorine;
   -The wear rate of the MMO anode is extremely low and uniform;
   -The mixed metal oxide can be operated at high current density, such as 2000A/m2.

* Jinhongtai ’s MMO Ribbon Anodes designed for use on both newly constructed above ground 

storage tanks, and existing tanks utilizing double bottom construction. They can be used in sands

 with various levels of moisture and salt contents without carbon back fill.


Titanium Conductor Bar

    Titanium Conductor Bar is highly resistant to corrosion in various environments. Titanium Conductor

 Bars are used along with MMO Ribbon Anodes and MMO Mesh Anodes for cathodic protection of

 above ground storage tank bottoms and in concrete structures.
