High-purity graphite has many high-quality characteristics, so it is used in industrial sectors such as metallurgical industry, mechanical equipment, electrical equipment, chemical plants, textiles, national defense and security. The main uses of pure natural high-purity graphite and synthetic high-purity graphite have a part that overlaps with each other, and there are certain differences.

In the iron and steel industry, pure natural flake graphite can be used to produce refractory and thermal insulation materials such as magnesium carbon brick and aluminum carbon brick due to its good oxidation resistance. Artificially synthesized high-purity graphite can be used as an iron-smelting electric grade, but the electric grade made of pure natural high-purity graphite cannot be used in the application of more stringent iron-making furnaces.

In machinery, graphite materials are generally used as raw materials for wear resistance and wetting. Pure natural flake graphite has good wettability and is commonly used as a preservative for grease. The equipment and equipment for transporting erosive materials generally use piston rings, seal rings and rolling bearings made of artificially synthesized high-purity graphite, without adding grease during work. Pure natural high-purity graphite and high-molecular material epoxy polymer materials can also be used in the industry, but the wear resistance is not comparable to artificial high-purity graphite.

Synthetic high-purity graphite has the characteristics of corrosion resistance, good heat transfer, and poor occupation rate. It is widely used in chemical industry to make machinery and equipment such as heat exchangers, reflection tanks, desulfurization towers, and filtering devices. Pure natural high-purity graphite and high-molecular materials epoxy polymer materials can also be used in the industry, but the heat transfer and corrosion resistance are not comparable to artificial high-purity graphite.
