Platinized Titanium & Niobium Anode Dimensionally Stable Anode

Platinum is widely used as electrodes in metal finishing industries, having special chemical & physical properties like high corrosion resistance, thermal conductivity and catalytic nature. 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.

Platinised titanium / niobium anodes are having the advantages of Low weight - good current resistance; Long life operation - maintenance free; Economical - due to low platinum requirements; High dimensional stability and low resistance; Highly suitable as auxiliary anodes of complex geometrical shapes.

Platinum is one of the six metals in the "Platinum" group of noble or precious metals, all of which are excellent catalyst materials. Platinum is conductive, chemically stable and highly resistant to oxidation and corrosion. It has a silvery-gray color and can be polished to a variety of finishes. Because of its high conductivity and low consumption rate, Platinum is an excellent anode material. Due to its high cost, Platinum is made practical for use by electroplating a thin layer over a high corrosion resistance substrate.

Since Titanium, Niobium and Tantalum substrates are having the ability to form an insulating oxide film under anodic conditions, they are all most commonly used as anode in ICCP. Among them, Titanium is less expensive; however, it has a much lower breakdown potential than Niobium or Tantalum. The titanium oxide breaks down at anodic potentials in the 12 V range.

Platinized titanium anode combines the excellent electrochemical performance of Platinum and higher anticorrosion property, comparing with the other soluble electrode and Lead anode.
