Carbon element is one of the most closely related and important elements in nature. It has the characteristics of multiple electronic orbits of SP, SP2 and SP3 hybrid. In addition, the anisotropy of SP2 leads to the anisotropy of crystals and other permutations. Therefore, carbon materials with carbon as the only constituent element have various

Due to the short supply of carbon products and high profit margin, the economic benefits of carbon enterprises are generally optimistic, Carbon products once had “black gold” “Carbon enterprises have sprung up all over the country and have grown rapidly to nearly 400. However, there are only more than 40 carbon enterprises with supporting processes

1. High temperature resistance: graphite is one of the most high temperature resistant materials known at present. Its melting point is 3850 ℃± 50 ℃ and its boiling point is 4250 ℃. Under 7000 ℃ ultra-high temperature arc for 10s, the graphite loss is the smallest, and the graphite loss is 0.8% by weight. It

When formulating high-speed machining process, the following aspects shall be comprehensively considered:   (1) Cutting parameters;   (2) Tool feeding mode;   (3) Tool geometry;   (4) The number of cutting edges and the overhang of the cutter bar;   (5) Cooling conditions;   (6) Clamping mode between tool bar and machine tool;   (7)

As one of the four main materials of lithium-ion battery, the specific capacity and working voltage of the negative electrode material directly determine the energy density and working voltage of the battery. Although silicon materials begin to move towards industrialization, the current mainstream negative electrode material is still graphite electrode materials, which has a low

Carbon materials are inorganic non-metallic materials dominated by carbon. Carbon materials are basically composed of non graphitic carbon, while graphite materials are mainly composed of graphitic carbon. Graphite is divided into natural graphite and artificial graphite.   Graphite material is mainly composed of polycrystalline graphite. Graphite is a kind of layered crystal with hexagonal plane
