Graphitization process is used to transform a carbon-rich material into graphite due to the application of heat. The initial carbon structure alters during heating causing carbon atoms to rearrange themselves into a crystalline lattice. This process generally occurs at high temperatures up to 3000 °C.

The process plays a significant role in the enhancing the material properties of carbonaceous materials. This results in an improved lubricity, oxidation resistance and thermal conductivity of components. Improved performance due to graphitization leads to the production of high-quality materials such as carbon graphite composites, graphite electrodes and is used for applications such as refining mechanical properties and machinability of iron alloys.

Although hard carbon and graphite are composed primarily of carbon atoms, they both exhibit different structures due to the arrangement of atoms. The crystal arrangement imparts the characteristics and material properties of a material even if they are made of the same element. In graphite, each carbon atom is bonded to three other carbon atoms, forming a flat sheet that is stacked on top of one another. The bonding along the length of the sheet is stronger than between each layer, hence, giving graphite its unique properties. Hard carbon, in contrast, is known as non-graphitizing carbon which unlike graphite has a more disordered and irregular structure where the layers are not as neatly stacked. This arrangement of atoms within hard carbon creates more intercalation sites or voids for positive charged ions and allows the material to store more energy. Hard carbon is useful for applications such as in batteries.

Carbolite offers solutions to graphitization technology for heat treatments that go up to 3000 °C. The furnaces offer graphite-based insulation material, heating element and retort material. Their robust design creates a system that can reach extremely high temperatures.
