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+ï¹¢→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 asÂ
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.Â
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
