The Characters of Diamond Coated Electrodes in Electrochemical Process The most important electrochemical properties of diamond coated electrodes are the very high corrosion stability in electrochemical applications and the extremely high overvoltage for water electrolysis, providing the possibility of producing strong oxidizing solutions with extremely high efficiency. Boron doped diamond films have been deposited on silicon, siliconcarbide, and different industrial electrode materials, like niobium, tantalum, titanium, tungste

How Platinum Electrodes are Used in Electrochemical Process? Platinum electrodes resist dissolution not only because of their position in the galvanic series as a noble metal but also because it forms an electrically conductive passivating thin surface film. The dissolution rate of platinum anodes in seawater is rated as about 2 x 10-6 kg / kiloamp-hour. The high expense of platinum combined with its very low rate of wear has to lead to it being primarily used as a thin film plating over less expensive metals. The most cost effecti

How Lead and Lead Alloy Anode is Used in The Electrochemical Process? Lead has complex electrochemistry when used as an anode material. Pure lead at low current densities dissolves into Pb2+ ions. The measured dissolution rate for pure lead under these conditions is 5 kg / kiloamp-hour. At higher current densities in seawater, lead chloride (PbCl2) forms at the surface. Lead chloride is an insulator that drops power efficiency radically as it thickens due to the IR voltage drop that occurs across the PbCl2 film. Under special condi

What Electrodes Material is Used for Electrochemical Treatment? The selection of electrode materials for electrochemical treatment must take into account issues such as cost, accessibility, stability at the required potentials, selectivity, composition, and pH of the reaction medium, nature of intermediates substances and products, and environmental compatibility. Care has to be taken in the proper selection since most electrodes are useful in only a limited range of potential and pH. With conventional metal electrodes, electroc
