Titanium anode/electrode (MMO) is made of precious metal iridium salt coated on titanium substrate
by high temperature sintering, is widely used in Electroplating, Chlor Alkali, Electro synthesis,
Water treatment and Metal Electrowinning. MMO Electrode preparation and application has been quite
mature, has been 40 years of history, has many advantages:
1, Technical characteristics
High efficiency current, excellent antibacterial corrosion performance; and long service lifetime;
2, High catalytic activity
It is known that the platinum-plated electrode is a high peroxygen potential electrode (1.563V,
relative to mercury sulphate) , while the MMO anode is a low oxygen evolution electrode(1.385V vs.
mercury sulphate) , More easily oxygen evolving. Therefore, it will be more save energy when using.
3, Non-polluting MMO
The anode coating is a ceramic oxide of noble metal iridium, which is a fairly stable oxide, hardly
soluble in any acid, and has an oxide coating of about 20 to 40 µm, generally speaking it with
less overall oxide coating . Therefore, the MMO anode does not cause contamination of the plating
solution, which is basically the same as the platinum-plated electrode.
4, Cost-effective
Obviously the MMO electrode is more economical than platinum-plated electrode.
5, Anode maintenance costs less. We don’t need to stop production to clean and replenish the
anode, replace the anode bag and re-coat the anode (increased productivity, reduced labor costs);
6, The insoluble anode service life depends on the type, current density and the contact with a
variety of electroplating chemicals.
