While there are a large number of written documents on nickel as a coating, there are very few dealing with nickel electroforming. This technology is an important consumer of nickel – about 5,000 tons per year worldwide – used to manufacture a wide range of articles (it is a manufacturing process, not a coating process). It is indeed the ONLY process that can produce certain very important products that are very often used in society. Most people are not aware of the process and its importance. It is a process that is indispensable for the production of compact audio discs and digital visual discs. Since the annual production of these items is estimated at about 4.000,000,000, you can see how important it is for our lifestyle today. Another very large application is the mass production of holograms.
Oxidation-reduction reactions also known as redox reactions for a shorthand term are typified by any chemical process that involves transfer of electrons between two species. The ubiquitous nature of redox reactions occurs over diverse systems ranging from industrial processes to chemical reactions encountered in everyday basic life functions. Based primarily on electrochemistry, the present article reviews the science of redox reactions with applications in some specific industrial and real life cases.
