The role and use of graphite

Graphite is an allotrope of carbon with various excellent properties, and is therefore widely used in many fields. The following are the main functions and uses of graphite:

Characterization and application of graphite materials

Graphite, as a unique carbon material, has many remarkable properties. Its excellent electrical conductivity, thermal conductivity and chemical stability make it show broad application prospects in many fields.In the field of batteries, graphite, as a negative electrode material, can efficiently store and release electrical energy, becoming an important part of lithium-ion batteries. In addition, graphite is

Many new main uses of graphite have already been developed and designed

Many new main uses of graphite have long been developed and designed with the development trend of scientific and technological progress. Graphite has many new main uses. High -purity graphite products are used for high -purity metallurgical industry, electronics industry, Chinese nuclear industry and mold processing; general graphite products can be used as a wall -building raw material for mining with aluminum electrolytic grooves, non -metallurgical tunnel furnaces, and non -ferrous metal furnaces. Calcium residual raw materials can be used as carbon increases for ironmaking industry. There are many types of carbon quality raw materials used to seepage nitrogen, including artificial synthesis of graphite, petroleum coke, casting focus, and pure natural graphite.Graphite products are at least within 2000 degrees. This is because carbon must be graphite at a high temperature natural environment of 2000-3300 degrees at a high temperature and natural environment of at least 10 days and

Factors affecting the gasification reaction of carbon materials

(1) Degree of graphitization: As the degree of graphitization of carbon materials increases, their activity towards gases decreases. The higher the final heat treatment temperature of carbon materials, the higher the temperature at which they begin to oxidize, so graphite products have a higher starting oxidation temperature than carbon products.(2) Structural state: Carbon materials with loose and porous surfaces are prone to react with gases. For example, the surface dense pyrolytic graphite treated at 3200 ℃ begins to oxidize in air at a temperature of 850 ℃, while the porous and loose charcoal on the surface begins to burn at 360 ℃.(3) Catalytic effect of impurities: Carbon materials contain impurities that have a significant impact on their gasification reaction, with varying catalytic effects. For example, iron, cobalt, nickel, copper, manganese, etc. are catalysts for the oxidation of carbon materials, while impurities such as boron, titanium, and tungsten have inhibitory effec

It is critical to properly clean up graphite molds

Like other objects, graphite molds must be cleaned up after a long -term application. This is also a key factor in carrying out maintenance of graphite molds, and after cleaning up, the next manufacturing can be carried out immediately. As a result, the cleaning of graphite molds is very critical.If you want to achieve good practical effects and improve work effectiveness, proper operation steps are also crucial. During the entire process of cleaning the graphite mold, professional equipment maintenance management is created in the connection between the requirements and the actual operation. In order to complete the cost benefits, you must pay more attention when cleaning up. Especially for the different positions of graphite molds, the selected cleaning method is also likely to have a difference.Properly grasp the cleaning method of graphite molds and operate in accordance with the actual operation, which can increase the use period of the machine and equipment at a very large level

The Future Market Prospects of Graphite Powder

Is ultra -fine graphite powder be microflashed?

The size of the material particles determines its name. As you ask questions, micro powder is micron -level powder. In the graphite industry, micro powder generally refers to the diameter of 10 ~ 45 microns. Inside, special graphite powder below 5 microns.Ultra -fine graphite generally refers to graphite with fine particle size. Its particle size is thinner than ordinary microflower graphite. It is generally less than 5um, and the general particle size of microflower graphite is about 10 microns. Qingdao Risheng graphite focuses on ultra -fine graphite production.The specifications of ultra -fine graphite powder are generally between them, mainly used in powder metallurgical destruction agents, graphite, battery negative electrodes, and additives for conductive materials.Graphite powder is divided into: nano graphite powder, colloid graphite powder, scales graphite powder, ultra -fine graphite powder. The number of graphite powder specifications from 50 mesh, and the types of graphite

How is high -carbon graphite made?

High -carbon graphite extraction method, flotation method is one of the most benefit of high -carbon graphite with low energy consumption and reagent loss and lowest cost of energy consumption and reagent loss in mineral purification. However, when the floating method is used, the graphite can only achieve unlimited progress. Regarding scales -shaped graphite, not only will it be unbuttoned to separate it, but it is not conducive to maintaining the large scales of graphite. To obtain high carbon -containing high carbon -based graphite, pure graphite is needed to use chemical method.(1) Pure method of high carbon alkaline acid. The carbon content after the purification of alkaliic acid method can reach more than 99 %. It has the characteristics of less one -time investment, high product grade, and strong process adaptability. It also has strong generality. The purity of non -metal mines can accept the benefits of alkaline acid method. The alkaline acid method is the most common essenti
