A platinized titanium anode is simply a titanium anode coated with platinum or platinum metal oxides. Platinized titanium anodes act as inert anodes and are non-consumable and long lasting.
Platinum is used in electrochemical cells because it is resistant to oxidation- it will not easily react, which makes in excellent as an electrode. Platinum, the most plentiful of the platinum group metals, has many uses due to its resistance to corrosion. In addition, it is extremely useful as a catalyst for oxidations, such as for the production of sulphuric and nitric acids. Also it is for hydrogenation as in the production of many pharmaceuticals and chemicals. In inorganic chemical industry platinum is widely used as the anode in a number of electrochemical processes.
Advantages of Platinum Anode:-
• Using platinum coated titanium electrode, the oxygen over potential is low, and it is not corroded by the electrolyte. The platinum metal oxides shows excellent electrolytic durability.
• Factory life, platinum coating is more stable, suitable for various environments and applications, the disadvantage is higher cost.
Features of Platinum Anode:-
• Flexible and application-specific design
• Production of complex shape anodes
• Energy saving potential
• Low weight (in particular expanded metal mesh anodes)
• Long service time even at high current density
• Dimensional stability, long durability of base material
• Replating possible
