Q: What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water: The first answer to the equation above is quite right, or it may be that a layer of calcium carbonate is attached to the surface of the electrode, which prevents the electrode from conducting and leads to an increase in resistance

Q: Which department in the steel plant needs graphite in large quantities?: For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.

Q: What kind of asphalt is better for natural graphite coating?: Graphite anode is mainly made of petroleum coke as raw material and coal pitch as binder. It is made by calcination, batching, kneading, pressing, roasting, impregnating, graphitization and machining. Conductive anode used for electrolysis equipment in electrochemical industry. Including: (1) anode plate for various chemical industries. (2) all kinds of anode rods.

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: Why is graphite a negative pole and copper is an anode?: The process of causing a chemical change by passing through a substance. Chemical change is the process in which material is lost or obtained by electrolysis (oxidation or reduction). Electrolysis is performed in an electrolytic cell. The electrolytic cell is composed of two electrodes, yin and Yang, which are respectively immersed in the solution containing positive and negative ions. The current into the negative electrode (cathode), are positively charged ions migrate to the cathode solution, and with the combination of electronic elements, become neutral or negatively charged molecules; negative ion transfer to another electrode (anode), electrons are given into neutral elements or molecules.

Q: How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done: Infeasible!Iron plating is not easy because two - valent iron is not well - controlled with ferric ironGenerally, metal plating with multivalent States is not well controlled

Q: Graphitized coke, graphite, broken, mixed up, how to export?: Graphite electrode pieces in different data definition of graphite scrap is different, some data and literature of the graphite particles are called not great pieces of graphite (such as graphite) and some say that graphite products have a certain size, into a block of graphite broken, we are here to say Shi Mosui is second, often called as the graphite block. The production of graphite from graphite products, graphitization and machining process. Graphite waste used as an additive and as a conductive material in the steelmaking and casting industries.

Q: Electrolysis of CuCl2 solutions with graphite electrodes: After energization, electrolysis occurs, not ionizationIonization does not require energization, and can occur in aqueous or molten state.

Q: What are pyrolytic graphite electrodes used for?: In 1960s, copper is widely used as electrode material, usage rate of about 90%, about graphite only 10%; in twenty-first Century, more and more users start using graphite as the electrode material, in Europe, more than 90% above the graphite electrode material is. Copper, the once dominant electrode material, has almost lost its advantages over graphite electrodes.

Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?: 9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.
