Spherical graphite

The spherical graphite is based on high -quality high -carbon natural scales graphite as the raw material. It uses advanced processing technology to modify the surface of graphite. The production is different, like an oval spherical graphite product.Ballog graphite material has good conductivity, high crystallization, low cost, high theoretical embedded lithium capacity, low charging potential and flat, and is an important part of the lithium -ion battery negative material. Replacement products have excellent conductivity and chemical stability, high charging capacity, long cycle life, and green environmental protection.The spherical graphite processing process is first to form initial products spherical graphite through rough, repair, magnetic selection and other processes in the spherical graphite workshop, and then enter the purified workshop and enter the high temperature and purify it into high purifiers.There are two main indicators to measure the quality of spherical graphite,

The Electronic Effect of Graphene

Graphene already exists in nature, but it is difficult to peel off a single layer structure. Graphene is stacked layer by layer to form graphite, with a thickness of 1 millimeter containing approximately 3 million layers of graphene. A pencil lightly scratches on paper, leaving traces that may be several or even just one layer of graphene.The carrier mobility of graphene at room temperature is about 15000 cm2/(V · s), which is more than 10 times that of silicon material and more than twice that of the known material indium antimonide (InSb) with the highest carrier mobility. Under certain specific conditions, such as low temperature, the carrier mobility of graphene can even reach up to 250000 cm2/(V · s). Unlike many materials, the electron mobility of graphene is less affected by temperature changes. At any temperature between 50 and 500K, the electron mobility of single-layer graphene is around 15000 cm2/(V · s).In addition, the semi integer quantum Hall effect of electron carriers

Natural graphite classification

The dense crystal graphite is also called block -like graphite. Such graphite crystals are obviously visible to the naked eye. The diameter of the particles is greater than 0.1 mm, which is concentrated in 0.1-1m/g than the surface area. This graphite is characterized by high quality. Generally, the carbon content is 60-65%, and sometimes 80-98%, but its plasticity and slipperyability are not as good as scales.

What are the effects of graphite products?

What are the effects of graphite products? The scope of graphite applicable is to produce artworks that can manufacture fire insulation materials and high -temperature raw materials. In recent years, fire prevention insulation and insulation materials have not been widely used in industrialized production. So what are the efficacy of graphite products? Beijing graphite pot manufacturers summarize the scope and efficacy of graphite products.Industries such as national defense and safety have been widely used, and graphite products have long been widely used in metallurgical industry, chemical enterprises, petrochemical equipment machinery equipment, high -energy physics, aerospace, electronic components, etc. High -purity graphite can be used to manufacture insulation bricks, tongs, constantly built -in powder, molding cores, mold casting, detergent and high temperature resistance, which is closely linked to the steelmaking industry.

How to choose the scale of scales graphite size

Scales graphite has good conductivity and thermal conductivity. It is widely used in sealing, lubrication, metallurgy, chemical industry and other industries. Different industries have different requirements for the specific parameters of scales graphite. Choosing the correct graphite graphite is closely related to its effect. Today, I will explain the correct method of choosing the graphite size of the scale:1. The effect of scale graphite particle size on expansionThe degree of particle size on the expansion of scales also has a certain effect. After experiments, the expansion rate of scales graphite is directly proportional to the particle size of graphite. The expansion graphite has a rich pore structure. The smaller the grain size of the graphite. The smaller, the lower the expansion coefficient, and vice versa. Therefore, in the fields of sealing and fire -resistant coatings, large -scale scales should be selected as materials.2. The effect of scale graphite particle size on smo

The position and role of carbon industry in the development of the national economy

Compared with large industries such as machinery, automobiles, electronics and electrical engineering, mining and metallurgy, railways, and transportation, the carbon industry is a small industry, but it occupies an important position and plays an important role in the development of the national economy in China. According to China's first five-year plan, 156 large-scale projects were newly built, of which the carbon industry accounted for two projects. For example, the development of the steel industry cannot be separated from carbon materials and products, especially electric furnaces for smelting alloy steel, which must have graphitized electrodes. Electrolytic aluminum production requires the consumption of 400-450kg of carbon anodes for each ton produced. In addition to ordinary civilian industries, carbon fiber composite materials have a wide range of applications in aviation, aerospace, nuclear energy, military and other fields, such as high specific strength, light weight, an

Do you know the development history of graphite?

Graphite occupies an important position in the industry, and because of its good performance, graphite is widely used in many industries, and its use effect is good, so it is loved by users. Some basic knowledge of graphite must be known to everyone. The following is the development history of graphite. Presumably very few people know this. So today, let us take a closer look. The following is the introduction made by graphite manufacturers.Graphite is a kind of carbide accidentally discovered in the laboratory by Acheson of the United States in 1891 when he was conducting molten diamond experiments. At that time, it was mistaken for a mixture of diamonds, so it was named emery. The industrial method of smelting graphite, also known as the Acheson furnace, is still in use today. The electric resistance furnace with carbonaceous material as the furnace core generates graphite by heating the mixture of quartz SIO2 and carbon.Several events about graphiteGraphite was first discovered in

What are the reasons for the low initial efficiency of lithium carbide graphite negative electrodes

1. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas

Which of the scale of the number of meters is more?

Scales graphite has many specifications. Different specifications are determined according to different goals. The number of scale graphite ranges from 50 ~ 12000 mesh. A specification of scales graphite, so why is the 325 -purpose scales graphite application very wide? The following Jinhui graphite editor will analyze it in detail:Scales graphite is a natural scales graphite as the processing raw material. After machinery, it can be crushed to 325 mesh graphite powder. The 325 -mesh scales graphite is purified and other processed. It can be processed into a carbon -containing 325 -mesh graphite powder with a carbon content of 99%or 99.9%. Such a 325 -mesh scales graphite has good conductivity, high temperature resistance, and lubrication performance. The use of high carbon -containing 325 mesh scales graphite is used in different industrial production areas.Graphite powder is processed and highly purified on the basis of scales graphite to remove impurities, so that the purpose of 32
