Uses of graphite plates

Graphite plates are an important industrial material with good electrical conductivity, high temperature resistance, acid and alkali corrosion resistance and easy processing. The following are the main uses of graphite plates:

Refractory materials: In the smelting industry, graphite plates are used to make graphite crucibles, as protective agents for steel ingots, and as magnesium carbon bricks for lining smelting furnaces512.

Conductive materials: In the electrical industry, graphite plates are widely used as electrodes, brushes, electric rods, carbon tubes, and coatings for television picture tubes, etc.414.

Wear-resistant materials and lubricants: In many mechanical equipment, graphite plates are used as wear-resistant and lubricating materials, which can slide at a speed of 100m/s in the temperature range of -200 to 2000℃ without or with less lubricating oil514.

Sealing materials: Flexible graphite plates are used as piston rings, gaskets, and sealing rings for centrifugal pumps, turbines, steam turbines, and equipment that transports corrosive media51014.

Corrosion-resistant materials: Graphite plates are used as utensils, pipes and equipment, which can resist corrosion from various corrosive gases and liquids and are widely used in petroleum, chemical industry, hydrometallurgy and other departments 514.

Heat insulation, high temperature resistance and radiation protection materials: Graphite plates can be used as neutron moderators in nuclear reactors, as well as rocket nozzles, missile nose cones, aerospace equipment parts, heat insulation materials, radiation protection materials, etc. 914.

Construction field: Graphite plates are heat-resistant and flame-retardant, and are widely used in the exterior wall insulation system of buildings 38.

Aerospace field: Graphite plates have the characteristics of electrical conductivity and high temperature stability, so they are widely used in the thermal control system of spacecraft. Graphite plates can be used as thermal protection materials to protect spacecraft from the high temperature caused by air friction when entering the atmosphere. They can also be used to make heat insulation boards, radiators, etc. 3.

Electronic industry: Graphite plates can be used as heat conduction plates, radiators, gaskets, etc. for electronic components due to their good electrical conductivity. At the same time, the low thermal expansion coefficient of graphite plates enables them to ensure the stability of electronic components in high temperature environments 3.

As nozzles for solid fuel rockets: Graphite is also used in the defense industry to make nozzles for solid fuel rockets11.

The above are the main uses of graphite plates. It should be noted that different types of graphite plates (such as high-purity graphite plates, electrode graphite plates, and flexible graphite plates) may have different application areas.
