Mixed Metal Oxide Coated Titanium Cylindrical Mesh Anode for Electro Chemical Process

MMO Titanium is mostly used as anAnode during electrochemical process. Titanium has peculiar properties. It is resistant to the passage of current into an electrolyte, but it has low resistivity when a second metal makes contact with it. If an attempt is made to use titanium as an anode in salt water, this resistance to the passage of current into the electrolyte immediately becomes apparent for an increasing anodic current is applied to it, the voltage required to force the current through the surface film rises until at the weakest points the film breaks down and intense local corrosion ensues.

Electrochemical process requires anodes. Mainly Iridium Based or Ruthenium based Titanium Anodes. MMO titanium anodes combine the excellent electrochemical characteristics of MMO with the good corrosion qualities of titanium.

MMO titanium is titanium that has been coated with a very thin layer of MMO, normally by electro decomposition process. The purpose of it is to provide a conducting medium that will not react with electrolytes. Iridium is very inert and doesn't readily react electrochemically, so you can do some very good electrochemistry with it. Titanium is used because of its high conductivity and ease in plating under electro deposition process.
