Titanium powder sintered hydrogen fuel cell anode sheet for H2

Titanium powder sintered hydrogen fuel cell anode sheet for H2 Platinum coated porous titanium electrode plate , 2 micron coated platinum porous titanium electrode plate, metal sintered porous titanium plate is a very good electrode material in the acidic medium. The product is used in Organic Electrolysis, such as cysteine, Cr3+, Cr6+, CN, and toxic substances, which can be used as the auxiliary electrode in electroplating industry, such as the auxiliary anode of Cr, auxiliary anode of electrolytic copper, auxiliary anode of electrolytic zinc, and so on. It is also used in the electrolytic cobalt and nickel. The characteristics of the products of the porous titanium electrode, 2 micron coated platinum porous titanium electrode plate and metal sintered porous titanium plate: The chemical properties of iridium are very stable. The corrosion of the metal, iridium high chemical stability to acid, insoluble in acid, only cavernous iridium will slowly soluble in Wang hot water. If it is a compact iridium, even boiling aqua regia and cannot corrode iridium; slightly affected by molten sodium hydroxide, potassium hydroxide and sodium dichromate to erosion. The general corrosion agent can not be corroded iridium. There is a strong tendency to form a complex compound. The main +2, +4, +6 valence. Platinum coated porous titanium electrode, 2 micron coated platinum porous titanium electrode plate, metal sintered porous titanium plate products: Element uses: pure iridium is used in the spark plug of the aircraft, it is used for making scientific instruments, thermocouple, resistance wire, etc.. As a alloy, it can enhance the hardness and corrosion resistance of other metals. Pure iridium is used for alloy, although it has a separate use, but this situation is relatively small, the form of dense metallic form in general as a spindle, crucible, or silk. The iridium processing into filamentous high cost, the iridium wire of the market price of up to 1000 yuan per gram, so iridium often alloy forms appear, it with platinum formed (PT IR of the 10% and 90%) alloy, due to expansion coefficient is extremely small, commonly used to make international standard meter, world kilogram is also made of platinum iridium alloy produced.
