Graphite is a natural inorganic material composed of carbon elements, which has good thermal conductivity, electrical conductivity, corrosion resistance, and lubrication properties. Therefore, graphite products have a wide range of applications in many industries, such as aerospace, electronics and electrical, metallurgical casting, chemical and pharmaceutical industries, etc. The following will introduce the processing of graphite products and some common applications.

The processing of graphite products mainly includes processes such as ore beneficiation, crushing, magnetic separation, flotation, and washing of graphite. The final graphite products are obtained through high-temperature sintering or graphitization treatment. The specific processing technology is as follows:

1. Ore beneficiation: Mechanical or physical methods are used to separate graphite ore to remove impurities and improve the purity of graphite.

2. Crushing: Crushing the ore to achieve a certain particle size requirement, which facilitates subsequent processing.

3. Magnetic separation: By the action of magnetic force, magnetic impurities in the ore are removed.

4. Flotation: By utilizing the physical properties of the ore, such as density and compositional differences, non graphitic substances in the ore are removed through the action of flotation agents.

5. Washing: Using physical or chemical methods to remove chemical impurities from ore and improve the purity of graphite.

6. High temperature sintering: The graphite ore treated as described above is subjected to heat treatment at high temperatures to promote grain growth and form a dense structure.

7. Graphitization treatment: The sintered graphite is subjected to higher temperature treatment to orient its lattice and improve its conductivity and thermal conductivity.

After the processing of graphite products is completed, the following aspects of processing and production can be carried out according to different application requirements:

1. Utilize the conductivity of graphite to make graphite electrodes. Graphite electrodes are widely used as electrodes in furnaces such as cast steel electric furnaces and cast iron electric furnaces in the power industry, as well as in electrolytic cells and other applications.

2. Utilize the lubricating properties of graphite to produce graphite lubricating materials. Graphite lubricating materials mainly include graphite oil, graphite grease, graphite gel, etc., which are widely used in lubricants, sealing materials, friction pairs and other fields.

3. Produce graphite seals. Graphite seals are made of graphite fiber paper or graphite interlocking plates, which have good corrosion resistance, sealing performance, and temperature adaptability. They are used for sealing chemical pipelines, pumps, valves, and other equipment.

4. Produce graphite powder and graphite slurry. Graphite powder is widely used in industries such as coatings, inks, and rubber, while graphite slurry is used in electronic slurry and graphite coatings in the electronics and electrical industry.

5. Produce graphite castings. The method of using graphite molds and molten iron for one-time casting to produce graphite castings is mainly used in the metallurgical casting industry for castings such as cast iron and cast steel.

In addition to the above applications, graphite products can also be used in various fields such as paper industry, electronics industry, photovoltaic industry, etc. In the paper industry, graphite paper can be used as a protective material to improve the flame retardancy and high temperature resistance of paper. In the electronics industry, graphite thermal interface materials are widely used in heat dissipation modules and integrated circuit heat dissipation. In the photovoltaic industry, graphite electrodes are used in the production of solar cells.
