The starting materials include lignite, coal or petrol coke, which are mixed with a binding agent such as tar or a plastic resin, and then annealed at 600 °C to 1 000 °C. This produces carbon graphites, which are used for applications such as slide bearings, sealing rings or pump components. In another optional manufacturing step, the graphitisation, these carbon graphites are annealed once again at up to 3 000 °C. This causes the individual graphite crystals to enlarge, causing an increase in density. Contaminants are burned off to improve purity.
