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

A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.

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

In anaerobic conditions, the ignition temperature is at least above 3000 degrees. There are many types of graphite, different types of ignition points, and the burning point of pyrolytic graphite...

Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?

Overhead wires, radiating the best conditions, allowed the current largest. The insulated wire in the house is laid in the wall, which has the worst heat release conditions and the smaller permissible current, so there are different safety currents.

Q:Graphite electrode press device

Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces

Q:What's the use of carbon?

High power graphite electrode. Allows the use of current density of 18 ~ 25A/ cm 2 graphite electrode, mainly used in steel-making high power arc furnace

Q:What is the application of wire cutting with graphite electrode?

With the development of science and technology, the machine manufacturing technology has undergone profound changes. Due to the social demand for diversification of products is more intense, more varieties, small batch production increasing proportion in WEDM by traditional processing equipment has been difficult to adapt to the processing of high efficiency, high quality, diversified requirements, CNC technology should be used

Q:Carbon graphite electrode and what is the difference?

Graphite electrode is a mixture of natural graphite and petroleum coke and asphalt coke. After being treated by high temperature graphitization, the material is composed of graphite;

Q:What does graphite electrode GSK mean?

Graphite board material is GSK, GSK refers to model specifications

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
