Due to its advantages of special chemical & physical properties like high corrosion resistance, thermal conductivity and catalytic nature, Platinum is widely used as anodes in metal finishing industries. Being a very expensive metal, instead of using solid form, platinum is deposited on the surface of titanium or niobium, occasionally on molybdenum by micron level layer. Electrodes [Anodes or Cathodes] are available with hanging hook, frame or band in the form of sheet, mesh, pipe, wire, rod and custom built. Platinised titanium anode is used in electrolytes having no fluoride. Platinised niobium anodes are used in electrolytes having fluoride, where we need better conduction (its conductivity is three times of titanium) and also it is suitable for Sulphuric acid chromium plating bath operated at current density greater than 75A / dm².
