Main uses of high-purity graphite

High purity graphite has many excellent characteristics, such as high strength, high density, high purity, high chemical stability, dense and uniform structure, high-temperature resistance, high conductivity, good wear resistance, self-lubrication, and easy processing, so it is used in metallurgical industry, mechanical equipment, electrical equipment, chemical plants, textiles, national defense and security, and other industrial sectors. The main uses of pure natural high-purity graphite and synthetic high-purity graphite overlap each other, and there are also some differences.

Differences between high-purity graphite and synthetic graphite with high-purity

High-purity graphite and synthetic high-purity graphite still have some differences in different industries.

In the iron and steel industry, pure natural flake graphite can be used to produce refractory and thermal insulation materials such as magnesia carbon brick and aluminum carbon brick because of its good oxidation resistance. Synthetic high-purity graphite can be used as the electric grade of iron making, while the electric grade made of pure natural high-purity graphite can not be used in the iron making heating furnace with strict standards.

In machinery, graphite materials are generally used as wear-resistant and moisturizing raw materials. Pure natural flake graphite has good wettability and is often used as a preservative for lubricating grease. The piston rings, sealing rings, and rolling bearings made of synthetic high-purity graphite are generally used for the machinery and equipment transporting corrosive substances, and there is no need to add grease during operation. Pure natural high-purity graphite and polymer materials epoxy resin polymer materials can also be used in the industry, but the wear resistance is not as good as that of synthetic high-purity graphite.

High purity graphite blank shall be free of oxidation, cracks, and appearance impurities. The surface defects edges and corners of the blank shall not exceed the provisions in the following table.

Synthetic high-purity graphite has the characteristics of corrosion resistance, good heat transfer, and poor occupancy. It is widely used in the chemical industry to make heat exchangers, reaction tanks, desulfurization towers, filtration devices, and other machinery and equipment. Pure natural high-purity graphite and polymer materials epoxy resin polymer materials can also be used in the industry, but the heat transfer and corrosion resistance are not as good as synthetic high-purity graphite.

Domestic enterprises should integrate resources and improve the position of China’s high-purity graphite production in the future international market by introducing foreign advanced technology, digestion, absorption, and re-innovation. Believe our products with high-quality can catch your eyes.
