Descripción del producto

In acid medium oxygen evolving reaction, available electrode material is extremely limited, but iridium-tantalum coated titanium electrode produced by Baoji Ruicheng Titanium Industry Co., Ltd. is an excellent electrode material. The product is applicable to electrolysis of organic matter such as cysteine, glyoxylic acid, succinic acid, etc, Cr3+﹢→Cr6+ electrolysis of indirect oxidation, sewage disposal to oxidize organic matter and toxic material in water, such as conversion of CN-, as well as functions as auxiliary electrode in electro-plating industry, such as  Cr plated auxiliary anode, auxiliary anode of electrolytic copper, auxiliary anode of electrolytic zinc, auxiliary electrode of cathode protection, etc. Furthermore, the product can be used in electrolysis of electrolytic cobalt and electrolytic nickel. 
Iridium has stable chemical performance and is a metal having the greatest ability of resisting corrosion. Iridium has extremely chemical stability to acid and is insoluble in the acid. Iridium will slowly dissolve in hot aqua regia when it is in sponge form, but will not corrode even in boiling aqua regia when it is in dense form, let alone normal corrosive. Iridium has intense tendency of forming coordination complex, and mainly includes *2, *4 and *6 valences.
Application of element: pure iridium is specifically used in spark plug of airplane, and is mainly adopted to manufacture scientific apparatus, thermo-coupling, resistance wire, etc. Used as alloy, iridium can enhance hardness and corrosion resistance of other metals. Pure iridium is mainly used in alloy, and is seldom used alone. When iridium is used alone, it is generally in the form of ingot, crucible or wire. High cost is required to process iridium into wire, and price of iridium wire is about ***0 RMB/g in the market. Alloy of iridium and platinum (*0% of Ir and *0% of Pt), with extremely low expansion coefficient, is generally used for manufacturing international standard meter, as well as kilogram meter in the world
