Q:Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?: What happens is oxygen etching negative pole: Fe-2e-=Fe2+ positive electrode: O2+2H2O+4e-=4OH-, of course, the current is produced.

Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?: Carbon deposition can cause insufficient combustion of gasoline and cause engine chattering.

Q:What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?: In the electrochemical process, the electrode should not affect the reaction on the working electrode, so platinum and graphite are often chosen

Q:800KVA and 12500 EAF transformer data graphite electrode furnace.: Graphite project: Project Description: steel furnace and iron smelting furnace, ferrosilicon smelting, electrolytic aluminum and so on, all use large surface graphite electrode.

Q:Why graphite can be used as conductive material?: Widely used as electrode, graphite, carbon brush, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating and so on in the electrical industry. The most widely used in the smelting of graphite electrode, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to around, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace used for the production of rigid sand is also made of graphite electrode as the conducting material of the furnace head.

Q:Is the anode of electrolytic water suitable for ordinary titanium wires?: Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.

Q:Specification for graphite electrodes commonly used in steel works: The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.

Q:How does graphite produce solar cells?: In addition, the Research Report of the first author, Massachusetts Institute of Technology Department of materials science and engineering postdoctoral Zhang Shenggen said, different from other semiconductor temperature has been rising continuously, the graphite electrode coating Zinc Oxide nanowires can be temperature controlled at 175 degrees celsius.

Q:Can graphite be used as an electrode for electrolysis of silver in silver nitrate?: Xiaoyi Liyang said the principle is correct, but can get silver? I think we can solve the problem if we take proper measures to get the silver elements, such as separating the anode and the cathode from the salt water!

Q:How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?: You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction
