[Chemical Knowledge]：The nature of graphite powder, use, upstream and downstream raw materials, storage methods, graphite powder is what to do

Graphite powder properties

Graphite powder is a carbon-based material with unique physical and chemical properties. Its molecular structure is a hexagonal honeycomb layered structure, so that it has good electrical and thermal conductivity. The graphite powder has a weak interlayer binding force, and thus is easily peeled off to form a sheet. Graphite powder also has the characteristics of strong chemical stability, high temperature resistance and good lubricity. Under high temperature conditions, graphite powder can maintain its stable chemical properties and is not easily corroded by acid and alkali. These properties make graphite powder an important material in many industrial applications.

Graphite powder use

Graphite powder is widely used in industry. Graphite powder is used as refractory material, conductive material and lubricant in metallurgical industry. Its high temperature stability and electrical conductivity make it excellent in the fields of electric arc furnace steelmaking and battery electrodes. In the machinery industry, graphite powder is often used in lubricants and sealing materials, especially in high temperature and high pressure environments, its lubrication effect is significant. Graphite powder is also widely used in the nuclear industry, aerospace industry and electronics industry. For example, graphite powder is used for neutron moderators and shielding materials in nuclear reactors, and as conductive coatings for electronic components.

Graphite powder upstream and downstream raw materials

The production of graphite powder mainly depends on natural graphite ore and synthetic graphite. After natural graphite ore is mined, graphite powder is made by crushing and screening. Synthetic graphite is a high-temperature graphitization process that converts carbon-based materials (such as petroleum coke or coal coke) into graphite. In terms of downstream applications, graphite powder is widely used in battery manufacturing, lubricating materials, conductive coatings and other fields. For example, negative electrode materials and conductive agents in lithium ion batteries are important application directions of graphite powder.

Graphite powder storage method

The storage of graphite powder requires special attention to moisture, oxidation and pollution prevention. Because graphite powder has a large specific surface area and is easy to absorb moisture, it should be stored in a dry and ventilated environment, preferably in a sealed container. Graphite powder is sensitive to oxygen, and long-term exposure to air may cause oxidation reaction and affect its performance. Therefore, the contact between graphite powder and air should be minimized. In order to prevent the graphite powder from being contaminated, the storage environment should be kept clean to prevent impurities from being mixed in, which will affect its purity and use effect.

market demand and development prospect

The market demand for graphite powder has benefited from the rapid development of new energy, electronics and high-end manufacturing industries. Especially in the field of lithium batteries, with the popularity of electric vehicles and energy storage equipment, the demand for graphite powder as a battery anode material continues to grow. The development of high-tech industries such as 5G communications, semiconductor manufacturing, and aerospace has also driven the market demand for high-purity, high-performance graphite powder. In the future, with the progress of science and technology and the expansion of application fields, the application of graphite powder will be more extensive, and the market prospect is very broad.

Environmental protection and sustainable development

The production and use of graphite powder need to pay attention to environmental protection and sustainable development. On the one hand, the production process of graphite powder may produce dust and wastewater pollution, so it is necessary to adopt advanced production technology and environmental protection measures to reduce environmental impact. On the other hand, with the increasing shortage of resources, how to improve the recycling rate of graphite powder is also an important issue. For example, in the process of recycling waste batteries, the recycling of graphite powder can effectively reduce the waste of resources and reduce production costs.

Technological innovation and future direction

In terms of technological innovation, the research of graphite powder mainly focuses on improving its performance and expanding its application range. The electrical conductivity, thermal conductivity and mechanical strength of graphite powder can be significantly improved by means of nanocrystallization and surface modification. For example, the development and application of graphene is an important breakthrough in the field of graphite powder. Graphene has been widely concerned for its excellent performance and is regarded as one of the keys to new materials in the future. The innovative application of graphite powder in the fields of energy storage materials, electronic materials and composite materials will further promote its market development.

Conclusion

Graphite powder has a wide range of applications in industry due to its unique physical and chemical properties. With the continuous advancement of technology and changes in market demand, the use of graphite powder will continue to expand, and its production and use will be more environmentally friendly and sustainable. In the future, graphite powder will play a more important role in new energy, electronics, aerospace and other high-tech fields, and promote the rapid development of related industries.
