Q:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found

The graphite part is called pyrolytic graphite. Stronger than ordinary graphite, strong oxidation resistance.

Q:Thermal expansion coefficient of graphite

In the graphite electrode, the national standard, the volume density in more than 1.60 of both high power graphite electrode, of course because of the national standard index is low now, the volume density of normal power graphite electrode factory can reach 1.65, such as Chengde and long carbon factory.

Q:The difference between graphite electrode and graphite rod

Graphite rod for non metal products, as carbon arc gouging cutting process in an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, is not easy fracture, suitable for metal cutting into required shape.

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 about graphite electrode high-temperature oxidation resistant coating?

Heat resistant coating is generally able to withstand 300 degrees below the temperature, commonly used aluminum heat-resistant paint, high temperature resistance can withstand higher temperatures, such as 800 degrees or more, commonly used silicone heat-resistant paint

Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?

Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining

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:What is the composition of petroleum coke and what is its use?

Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.

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:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.

Indeed, the original battery electrode potential using two different electrodes, produce potential difference, so that the electron flow generated current. Graphite is used as an electrode because of its excellent electrical conductivity and stability
