Platinum is a precious metal having very good physical and chemical properties such as

          High corrosion resistance

        Thermal conductivity

        Catalytic nature

As it is very expensive, platinum cannot be used in its solid form as an anode. So that Platinised Anodes (Pt Anode) are produced by plating platinum (Pt) on a specially treated precious metal (Titanium / Niobium / Tantalum / Zirconium) substrate by means of electrodeposition process.

So, platinized anodes are economical as well as it retains the superior physical and chemical properties of platinum.

According to the substrate material used, the platinized anodes are called as
