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