Graphite can also be used to produce heat dissipation materials, sealing materials, thermal insulation materials, and radiation protection materials. Graphite functional materials are widely used in metallurgy, chemical industry, mechanical equipment, new energy vehicles, nuclear power, electronic information, aerospace, national defense and other industries.

The conductivity of graphite is 100 times higher than that of ordinary nonmetallic ores. The thermal conductivity is higher than that of steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature, and even at extremely high temperatures, graphite becomes an insulator. The reason why graphite can conduct electricity is that each carbon atom in graphite and other carbon atoms only form three covalent bonds, and each carbon atom still retains one free electron to transfer charge.
