Graphene is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes. It can be considered as an indefinitely large aromatic molecule, the ultimate case of the family of flat polycyclic aromatic hydrocarbons.Graphene and its band structure and Dirac cones, effect of a grid on doping Graphene has many unusual properties. It is about 200 times stronger than the strongest steel. It efficiently conducts heat and electricity and is nearly transparent.[3] Graphene shows a large and nonlinear diamagnetism,[4] greater than graphite and can be levitated by neodymium magnets. Scientists have theorized about graphene for…

Graphite materials can be divided into natural graphite and artificial graphite, natural graphite powder and because more shape so its application is limited, so the development of high pure graphite becomes more and more important; the application of high purity graphite in the photovoltaic production with the rapid development of photovoltaic industry in recent years and the rapid warming. With the rapid development of solar photovoltaic industry, the import of raw materials and polysilicon monocrystalline silicon solar battery demand is increasing in recent years, a large scale production of monocrystalline silicon polysilicon processing factory and processing factory as needed so like bamboo shoots after a spring rain built; production of monocrystalline silicon and polycrystalline silicon raw materials are increasing, and…

The graphite electrode must be stored in a clean and dry room. If the graphite electrode is pilled up outdoor, it must be covered with the waterproof cloth and the floors of the pile is prohibited more than In the delivery of graphite electrodes, a waterproof cloth must be covered on the graphite electrodes. When workers are delivering and pilling up graphite electrodes by forklift, collision is prohibited. Only one floor is allowed put each time, and the workers must pay more attention to the balance of the graphite electrodes, it can avoid the graphite electrodes sliding and broken When loading and unloading the graphite electrodes by crane, a steel wire must be used as assistant tool. Hooking the bend…
