Q:What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?

1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large

Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?

For example, according to connection of the electrode, which can be divided into two types of unipolar and bipolar type electrolyzer (see photo). The electrode is connected with the DC power supply parallel polarity monopolar electrolyzer, electrodes on both sides of the same, at the same time as anode or cathode. At the same time as the positive and negative electrode bipolar type electrolyzer ends respectively with DC power supply connected, as anode or cathode. The current through the electrode through the electrolysis cell in series, each side of the intermediate electrode as the anode, the other side is the cathode, so it has a bipolar electrode. When the total area at the same time, the current bipolar type electrolyzer is small, high voltage DC power supply, the required investment ratio monopolar, bipolar type filter press used. The general structure, more compact. But easy to leakage and short circuit, slot structure and operation management is more complex than the monopolar type. The monopolar electrolyzer section is generally rectangular or square, cylindrical covers a large, empty The utilization rate is low and the adoption rate is less

Q:The difference between graphite electrode and graphite rod

The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.

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:The future of graphene

Field of semiconductor materials. Graphene is considered to be an ideal material for replacing silicon. A large number of powerful enterprises have developed graphene semiconductor devices. The Han Guocheng Institute has developed a highly stable n type graphene semiconductor that can be exposed to air for a long time. Graphene silicon optoelectronic hybrid chip developed by Columbia University has broad application prospects in optical interconnection and low power photonic integrated circuit. IBM researchers have developed graphene field effect transistors with cutoff frequencies of up to 100GHz, with frequency performance far superior to the cut-off frequency of the most advanced silicon transistors of the same gate length.

Q:Classification of graphite electrodes

Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.

Q:I remember the more lively metal, the electron?

C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate

Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?

The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!

Q:How to solve the problem of graphite electrode being crushed during electrolysis

I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive

Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?

Can't。 During electrolysis, there is depletion of sulfite ions.
