Q: Why use platinum ferroalloy instead of iron as electrode?
General industrial grade silicon dioxide, because the preparation technology is different, can be divided into two types, one is dry, sintered (Fume Type), a wet precipitation type (Precipitated Type), and two of the surface area, the surface with hydroxyl (-OH) are the same, in general, the former the latter is more, less, the two surface has the tendency of hydrophilic, as for lipophilic polymer, such as paint, rubber... Etc.,... If the silica surface pre rendered hydrophobic, has a good effect.
Q: Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
In theory, as long as a certain temperature is reached, any substance can be burned, and the diamond is converted to graphite at 2000~3000 DEG C under anaerobic conditions. That is to say, graphite (flake graphite)
Q: The use of graphite as an electrode in alumina electrolysis
Graphite acts as an electrode:The electrical conductivity of graphite, the electrode itself must be electrically conductive;When graphite acts as an anode, it acts as a reducing agent and displaces an element of aluminum in a chemical reaction;Graphite is cheap and cost saving.
Q: Specification for graphite electrodes commonly used in steel works
In general, the graphite electrode used in steelmaking furnace is mostly made of ordinary power and high power graphite electrode. Now, the use of ultra high power graphite electrode increases year by year, accounting for almost half of the graphite electrode.
Q: The difference between graphite electrode and graphite rod
The two materials are different.Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
Q: How does graphite produce solar cells?
Gerrit J said: "despite the modifications, but the inherent nature of graphene remains unchanged, is a significant advantage of composite materials."
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: What are the losses in graphite electrode?
In EDM, discharge principle is to remove the workpiece material by using the tool and the workpiece anode spark discharge explosion, spark discharge is bidirectional, not only will the workpiece removal part, forming processing, will cause some loss of electrode. Electrode loss is one of the main causes of machining errors in machining, and is an important technical parameter affecting the accuracy and quality of EDM
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: I remember the more lively metal, the electron?
Metal ion is more inert electron, graphite electrode for electrolytic salt solution containing the same amount of substance A and C two metals, C first precipitated, so C is copper. In a dilute sulfuric acid with H2 precipitation, certainly not a copper. The more active metal betatopic ability is strong, have the corresponding ion electronic ability weaker. First metal ions corresponding to metal electrons are not active.
