Industrial Metallurgy

• Steelmaking: In the steelmaking process, graphite electrodes are extensively utilized. They conduct electricity to generate the high temperatures required for melting and purifying steel in electric arc furnaces. Graphite's excellent electrical conductivity and high melting point make it possible to endure extremely high temperatures without melting or deforming, thus ensuring the smooth progress of the steelmaking process.
• Non-ferrous Metal Production: In the production of non-ferrous metals like aluminum and copper, graphite products are used as lining materials for smelting furnaces and as crucibles. Graphite's good thermal stability and chemical inertness prevent it from reacting with the molten metal, ensuring the purity of the metal and the service life of the equipment.

Chemical Industry

• Chemical Reactor: Graphite heat exchangers and reactors are widely used in the chemical industry. For instance, in the production of hydrochloric acid and sulfuric acid, graphite reactors are employed for carrying out chemical reactions. Graphite's corrosion resistance and good thermal conductivity enable it to effectively control the reaction temperature and prevent the reactor from being corroded by the corrosive chemicals.
• Electrolytic Cell: In the electrolysis process of the chemical industry, graphite electrodes serve as anode and cathode materials. In the electrolysis of brine to produce chlorine and caustic soda, graphite electrodes play a crucial role. Graphite's electrochemical stability and good electrical conductivity ensure the efficient operation of the electrolytic cell and the quality of the electrolysis products.

Mechanical Industry

• Mechanical Sealing: Graphite sealing rings and gaskets are commonly used in mechanical equipment for sealing. In pumps, compressors, and other equipment, graphite sealing products can effectively prevent the leakage of liquids and gases. Graphite's self-lubricating property and good wear resistance reduce the friction between the sealing surfaces, enhance the sealing effect, and prolong the service life of the equipment.
• Lubricant Additive: Graphite powder can be used as an additive in lubricating oils and greases. In high-temperature, high-speed, and heavy-load working conditions, the addition of graphite powder to lubricants can significantly improve the lubricating performance, reduce wear and tear, and prevent the equipment from seizing up and overheating.

Aerospace and Defense

• Aerospace Components: Due to its lightweight, high strength, and excellent thermal stability, graphite composites are increasingly being used in the aerospace field to manufacture aircraft parts, such as wing skins, fuselage structures, and engine components. These graphite composite components can effectively reduce the weight of the aircraft, improve its fuel efficiency and flight performance, while ensuring the reliability and safety of the aircraft.
• Missile and Satellite Equipment: In missile and satellite equipment, graphite products are used in the manufacturing of thermal protection systems, electrical insulation components, and attitude control systems. Graphite's high-temperature resistance and good electrical insulation properties ensure the normal operation of the equipment in the harsh space environment and improve the reliability and accuracy of the missile and satellite.

New Energy Industry

• Lithium-Ion Batteries: Graphite is a key material in the negative electrode of lithium-ion batteries. Its layered structure can store and release lithium ions, and it has good electrical conductivity and chemical stability, which can improve the energy density and cycle life of the battery.
• Fuel Cells: In fuel cells, graphite bipolar plates are used to separate the anode and cathode, conduct electricity, and distribute gases. Graphite's good electrical conductivity, corrosion resistance, and gas permeability make it an ideal material for fuel cell bipolar plates, which can improve the performance and durability of the fuel cell.

Nuclear Industry

• Nuclear Reactor Moderator: Graphite is used as a moderator in nuclear reactors to slow down neutrons and control the nuclear fission reaction. Its ability to scatter neutrons without absorbing them makes it an important material for maintaining the normal operation of nuclear reactors.
• Nuclear Fuel Element: Graphite is also used in the manufacturing of nuclear fuel elements. It serves as a cladding material to protect the nuclear fuel and prevent the leakage of radioactive substances. Graphite's high-temperature resistance and radiation resistance ensure the safety and stability of the nuclear fuel element.
