- Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
- Graphite rod refers to graphite rod without processing. A graphite electrode refers to a finished product.
- Q:National standard for graphite electrodes
- Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB
- Q:Can graphite be used as an electrode for electrolysis of silver in silver nitrate?
- If it is molten, it can be made out of silverFor solution, only AgNO3+H2O== electrolysis ==Ag+HNO3+O2 is analyzedWhen the HNO3 concentration is enough, it will continue to react with Ag.... So you can't get Ag elements.
- Q:What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?
- Carbon electrodes, however, are less likely to be less controllable because of their microstructure, or have some effect on the electric field, if they are sensitive signals
- Q:What kind of asphalt is better for natural graphite coating?
- Special graphite mainly to high quality petroleum coke as raw material, coal tar or synthetic resin as binder, the raw material preparation, mixing, kneading, pressing, crushing, mixing, molding, roasting, soaking, repeatedly repeated purification and graphitization, and made the processing machine. It is generally used in the aerospace, electronics and nuclear industry sectors. It includes pure graphite, high purity, high strength, high density and pyrolytic graphite.
- Q:What about graphite electrodes for steel mills?
- The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
- Q:How to solve the problem of graphite electrode being crushed during electrolysis
- There's no way. It's an industrial problem, and that's how graphite works.
- 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
- Q:What does graphite electrode GSK mean?
- Graphite board material is GSK, GSK refers to model specifications
- 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.
