Titanium electrode (anode and cathode)

The electrode is made from a base and a coating.

Among many materials tested, the choice of the support, or substrate as you say in scientific language, has fallen on Titanium.Titanium has in fact the features required in order to receive the coating, to resist the chemically aggressive environments of the processes and it’s suitable for the current’s conduction.Another advantage of Titanium is that it can be worked in a wide range of shapes: sheets, nets, tubes, wires, complex manufactured products etc.The electrode was born from the combination of coating and Titanium, which has afterwards taken different commercial names: DSE - DSA - MMO etc...



The coating

It’s a very thin layer, a few microns, which covers the titanium’s surface in the areas where the anodic reaction takes place.

It’s composed by oxides, in variable percentages, of noble metals belonging to the Platinum family.In particular Ruthenium and Iridium are the main elements used, mixed with others within the same family: Palladium, Rhodium, Platinum.The formation of the coating takes place through the application of a solution of the above described salts’ elements and a subsequent high temperature thermal treatment to create the oxide.Each application or “coat” is a cycle during which a fraction of the prearranged coating’s quantity settles. The number of cycles is subject to the final noble metal’s load, which, in turn, is in relation to the type of final use it’s designed for.There are many formulations or “recipes” for coating, each of which is specific for its final use.You can distinguish between two families: anode and cathode coating.Among the anode coatings you can distinguish between: coating for Chlorine evolution, coating for Oxygen evolutionor mixed coating.The key component or the “catalyst” of the coating for Chlorine evolution is Ruthenium Oxide; for Oxygen evolution it is Iridium Oxide.Membrane cell cathode coatings are based on Ruthenium Oxide or Platinum, mixed with Palladium, Rhodium.
