What is high-purity graphite powder and what does it do?

Overview of High Purity Graphite

High-purity graphite refers to graphite powder of high-purity graphite with a carbon content of more than 99.9%. This high-purity graphite has good electrical conductivity, lubricity, high temperature resistance, wear resistance, etc.

High-purity graphite, also known as flake high thermal conductivity carbon powder, is an ideal inorganic non-metallic material with high strength, good thermal shock resistance, high temperature resistance, oxidation resistance, low resistance, corrosion resistance and other characteristics. For the manufacture of heating elements, structural molds, crucible plates for melting high purity metals, single crystal furnace heaters, EDM graphite, sintering molds, tube anodes, metal coatings, graphite crucibles for semiconductor processes, graphite anodes for launch tubes, thyristors, Mercury arc, power grid, etc.

High-purity graphite has the characteristics of high strength, high density, high purity, high chemical stability, dense and uniform structure, high temperature resistance, good electrical conductivity, good wear resistance, good self-lubrication, and easy processing. It is widely used in metallurgy, chemical industry, etc. , aerospace, electronics, machinery, nuclear energy and other industrial fields. In particular, large-size, high-quality, and high-purity graphite as an alternative material has broad application space and broad application prospects in the field of high-tech.

There are two purification methods for high-purity graphite. One is wet purification, including flotation method, acid-base method and hydrofluoric acid method. The second is fire purification, including chlorination roasting and high temperature.

High Purity Graphite Applications

High-purity graphite is widely used in advanced refractories and coatings in the metallurgical industry, refractory stabilizers in the military industry, pencil leads in the light industry, carbon brushes in the power industry, electrodes in the battery industry, catalyst additives, etc. in the fertilizer industry. High-purity graphite can be further processed to produce high-tech products such as graphite milk, graphite sealing materials and composite materials, graphite products, and graphite wear-resistant additives. Has become an important industry of non-metallic products.

1. Lithium battery industry

Natural graphite and artificial graphite are the main sources of graphite anode materials. Artificial graphite usually needs to go through processes such as calcination, carbonization, high temperature graphitization, and coating; natural graphite mostly adopts alkali metal acid selection, ultra-high temperature purification, surface treatment and other processes. Whether it is natural graphite or artificial graphite, it must be processed by graphite chemistry or Only high temperature cleaning can become the cathode material for lithium battery production. At present, high-temperature graphite purification technology and high-temperature graphitization technology have become the key technologies in the research field of graphite anode materials.

2. Graphene industry Compared with various preparation methods of graphene, graphite oxide reduction method will become the most promising method for synthesizing graphene and its materials. The main raw material of the graphite oxide reduction method is high-purity natural flake graphite.

3. Isotropic nuclear graphite industry

Since high-purity isotropic natural microcrystalline ink is an ideal raw material for atomic graphite, it is particularly important to broaden the raw material source of high-purity isotropic natural microcrystalline ink.

4. Synthetic diamond industry

Natural flake graphite powder is the main raw material for synthetic diamond. Scientists have proved that the purity of graphite powder and the degree of graphitization of graphite powder have an important impact on product quality. Selecting high-purity graphite raw materials and selecting an appropriate degree of graphitization will be the only way to improve the quality of synthetic diamond products.

5. Military graphite bomb industry

High-purity graphite is the raw material for the production of graphite bombs.

6. Flexible graphite industry

In summary, flexible graphite has unique use value and broad development prospects. However, in the production process, there are requirements for purity. Chemical acid purification often destroys or affects excellent material properties. High temperature physical refining has obvious advantages.

7. Other industries

Natural high-purity graphite powder has the advantages of high temperature resistance, good electrical and thermal conductivity, lubricity, good chemical stability, and good wear resistance. It can be used as a raw material for synthesizing crystalline silicon carbide and boron carbide. Machinery and other industrial fields have a wide range of applications.

To sum up, the market prospect of high-purity graphite powder is broad. If the 20th century was the age of silicon, carbon would be one of the fastest-growing and most versatile materials of the 21st century. Lithium battery anode materials, graphene materials, isotropic nuclear graphite, synthetic diamond, flexible graphite and other high-grade carbons play an increasingly important role in people's life, production and military.
