Tiaano offer Platinum plated Copper Anode, Platinum Plated Titanium anodes & Niobium Anodes (Platinum Plated Electrodes) for various research and developments. Many article provides a history of platinised anodes by reviewing innovations in the, electroplating, electro galvanizing, electro winning, chlor-alkali industry etc.... These anodes are attractive for numerous reasons (e.g., long life and educed energy consumption), but they must still overcome the hurdle of cost to gain wider acceptance for applications in the various process industries.

Chemical Behavior of Platinum and Titanium:-

Platinum is preferred on an anode's outer surface because it is highly resistant to corrosion and can ensure current flow in most electrolyte media without leading to the formation of an insulating layer on itself. Because it doesn’t corrode, it doesn’t produce corrosion products and hence the consumption rate is very low.

Titanium shows reasonably good resistance to a marine environment (seawater in particular). It does not react with concentrated (80%) solutions of metallic chlorides. However, it is susceptible to attack by hydrofluoric acid (HF) and hot hydrochloric acid (HCl) of higher concentrations. Even hydrogen peroxide and hot nitric acid can attack titanium. Oxidizing agents normally do not attack titanium because it readily forms a protective oxide coating. However, non-oxidizing substances such as sulfuric acid (above 5% concentration) and phosphoric acid (above 30%) can attack titanium. From a hydrogen embrittlement point of view, titanium fares better than tantalum as an anode material.

Chemical Behavior of Copper:-

Copper is a reddish metal with a face-centered cubic crystalline structure. It reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure, so it as a nice reddish color. It is malleable, ductile, and an extremely good conductor of both heat and electricity. Copper has low chemical reactivity. So people are using platinum plating on copper, this coating / plating protects the metal from further attack.
