Manufacturing process of extruded graphite. 1. COKES. Coke is a component produced in oil refineries by heating hard coal (600-1200°C). This process takes place in a specially designed coke oven, using combustion gases and limited oxygen availability. It has a higher calorific value than conventional fossil coal.
In this process, agglomerated graphite grains are produced for use as carburizer and carbon additives. Intercalation. Due to its extreme anisotropy, the graphite crystal enables salts to be intercalation in its structure. When heated, these salts evaporate, causing the disruption of inter-planar connections, "expanding" the graphite.
