1. Introduction MMO anode flexible body is coated with a mixed metal oxide IO2 / tantalum oxide Ta2O5 titanium-based anode, the anode of working life and the rated current is set by the anode body. Anode body is composed of a continuous matrix composed of titanium. Coating on the titanium substrate is able to adapt to heat environment, a stable crystal structure, having good conductive properties and catalytic iridium / tantalum oxide mixture, titanium anode substrate is in accordance with ASTM, ASTM B-265, DIN 3.7035 Standard Certification of a titanium. MMO main anode titanium base must not employ copper material. That mixed metal oxide coating on a titanium base must not coated copper surface. 2. The main technical parameters of the anode as follows: anode size (no backfill) ≥0.8mm anode weight 0.7Kg / m anode design life of 25 years in the carbon anode backfill feed consumption rate of 5 mg / Ann in metal oxide coating. The maximum operating current density with lower thickness ≥6g / m2 carbon backfill soil environment when <100A / m2 maximum current output 16mA / ft (52.5mA / m) metal oxide resistivity (ohm / cm) 10-5 ohm / contact resistance ≤0.9milli-ohms resistive anode anode cm cable ≤0.007 ohm / cm
